Bedrock is the solid rock at or below the land surface. Over much of Ireland, the bedrock is covered by materials such as soil and gravel. The Bedrock maps show what the land surface of Ireland would be made up of if these materials were removed. As the bedrock is commonly covered, bedrock maps are an interpretation of the available data. Geologists map and record information on the composition and structure of rock outcrops (rock which can be seen on the land surface) and boreholes (a deep narrow round hole drilled in the ground). Areas are drawn on a map to show the distribution of rocks. The Geological Lines show the details of the structural geology; faults, folds and unconformities. Faults and folds are the result of great pressure being applied to rock across a whole continent or more. These rocks will either break under the pressure, forming faults, or they will bend to form folds. Faults are recorded in the Geological Lines layer as lines where the break in the rock meets the surface. Folds are shown only using the lines of their axes, synclinal (where the rock folds downwards) and anticlinal (where the rock folds upwards). Unconformities are where there is a gap in the rock record, typically where rock has been eroded away in the past and a new rock deposited on top.Geologists map and record information on the structural geology. Lines are drawn on a map to show the location and extent of these structures. The structural symbols layer is used to describe the geology of an area through dip and strike information. Dip and strike describe the behaviour of the rock bedding plane. To describe a geometric plane two values are required; the angle from horizontal that it is dipping and the direction that it is dipping. Geologists describe the dip direction by the strike value; this is the azimuth perpendicular to the steepest dip of the plane.The measurements that this layer contains give information about the geometry of the rock units under the ground. These measurements are the only way to see if the rocks are folded and faulted and how. With this information we can also start to see why the rocks have the shapes that they do.In terms of time scale in geology, Quaternary is the present-day time and it began 2.6 million years ago. A lot of this time period relates to the Ice Age.Quaternary sediments are the soft material that has been deposited during this time. In Ireland much of this is related to the movement of glaciers and ice sheets. The main types of sediments shown on the map are tills (boulder clays), gravels, sands and peat. Over most parts of Ireland, these sediments cover the bedrock (solid rock at or below the land surface).Geologists map and record information from the shallow sediments which can be seen at or near the surface. This information along with boreholes (a deep narrow round hole drilled in the ground), geophysical data (information on the physical properties of the Earth's surface and subsurface e.g. magnetics, gravity and electromagnetics) and geochemical data (chemical properties) is used to create the map. Areas are drawn on a map to show where sediments are found.Quaternary geomorphology is the record of landscape features that were created in the last 2.6 million years. In Ireland, movement of glaciers and ice sheets created many of these features. The main features included are; erratic dispersion; landforms created under ice; landforms created at the ice margin and landforms created by mountain ice.An erratic is a rock which has been moved by ice and deposited in another location. Erratics are identified as the erractic rock type is different to the usual rocks found in that location. Geologists study the composition of erratics and can determine where the rock came from (the source). Once the source is known, the direction of ice flow can be determined (Inferred Erratic Path). The end of these erratic flow paths are termed erratic limits.Subglacial landforms are created beneath the ice. They were created during ice expansion. An example of these are drumlins. Drumlins are smooth, oval-shaped hills, shaped like a half-buried egg. They are made up of glacial till. As the glaciers retreated, they left these deposits behind. The exact process of drumlin formation is unknown. Mega-scale glacial lineations, like drumlins, are typically smooth hills of subglacially-deposited material, but are much longer. They are produced beneath zones of fast-flowing ice. Striae (Glacial striations) are scratches or gashes cut into bedrock by glacial movement, usually by particles embedded in glacier ice. They provide a reliable record of ice flow direction.Deglacial landforms are created at the ice margin. They were created during ice retreat. A moraine is material left behind by a moving glacier. Kame terraces, deltas and fans are all ice marginal landforms deposited by water issuing from a glacier.Landforms created by mountain ice include corries and trimlines. A corrie (cirque) is a half open, steep-sided round hollow made in the side of a mountain by the action of a glacier. A trimline is a clear line on the side of a valley formed by a glacier. The line marks the most recent highest extent of the glacier. The line may be visible due to changes in color to the rock or to changes in vegetation on either side of the line.Geologists map and record evidence during field visits, from air photographs and from Digital Elevation Models (DEMs). This data along with boreholes (a deep narrow round hole drilled in the ground) and geophysics help to create the map. Areas are drawn on a map to show where features are found, lines are drawn to show the direction of other features and some features are shown as points.These are vector datasets. Vector data portray the world using points, lines, and polygons (areas).

This digital map database is compiled from unpublished data and new mapping by the authors, represents the general distribution of surficial and bedrock geology in the mapped area. Together with the accompanying pamphlet, it provides current information on the geologic structure and stratigraphy of the area. The database delineates map units that are identified by age and lithology following the stratigraphic nomenclature of the U.S. Geological Survey. The scale of the source maps limits the spatial resolution of the database to 1:24,000 or smaller.

This data release presents geologic map data for the bedrock geology of the Aztec 1-degree by 2-degree quadrangle, New Mexico. Geologic mapping incorporates new interpretive contributions and compilation from published geologic map data sources primarily ranging from 1:24,000 to 1:50,000 scale. Much of the geology incorporated from published geologic maps is adjusted based on digital elevation model and natural-color image data sources to improve spatial resolution of the data. Spatial adjustments and new interpretations also eliminate mismatches at source map boundaries. This data set represents only the bedrock geology; deposits of unconsolidated, surficial materials that are typically, but not exclusively, Quaternary in age, are not included in this database. Bedrock in the context of this database includes all metamorphic, sedimentary, and igneous rocks regardless of age. Bedrock geology is continuous to the extent that map units and structures can be appropriately constrained, including throughout areas overlain by surficial deposits. Line features that are projected through areas overlain by surficial deposits are generally attributed with lower identity and existence confidence, larger locational confidence values, and a compilation method in the MethodID field indicating features were projected beneath cover (see Turner and others [2022] for a description of MethodID field). Map units represented in this database range from Paleoproterozic and Mesoproterozic metamorphic and intrusive rocks to Pliocene and Quaternary sedimentary and volcanic rocks. Map units and structures in this data set reflect multiple events that are significant at regional and continental scales including multiple Proterozoic accreted terranes, magmatic episodes, supracrustal depositional environments, and continental margin environments, Ancestral Rocky Mountains, Laramide orogeny, Southern Rocky Mountains volcanism, and Rio Grande rift in the Phanerozoic. Map units are organized within geologic provinces as described by the Seamless Integrated Geologic Mapping (SIGMa) (Turner and others, 2022) extension to the Geologic Map Schema (GeMS) (USGS, 2020). Geologic provinces are used to organize map units based on time-dependent, geologic events rather than geographic or rock type groupings that are typical of traditional geologic maps. The detail of geologic mapping is approximately 1:100,000-scale depending on the scale of published geologic maps and new mapping based on field observations or interpretation from basemap data. The database follows the schema and structure of SIGMa (Turner and others, 2022) that is an extension to GeMS (USGS, 2020).

Map server application presents the results of the geological maps of the Czech Republic at a scale of 1 : 500,000 (GEOCR500). Maps describe bedrock geology and also (in Czech version of the application) additional derived maps: radon risk, engineering–geological zones and quaternary geology.

The Bedrock Index provides a spatial record of the location of all Bedrock maps published by the Geological Survey of Canada and hosted on Geoscan. The index has three "series" of maps; CGM, A series, and preliminary maps. In cases where there have been multiple editions of a map, the most recent record is reported in the Bedrock Index attribute table. Maps published in Open File documents are not recorded in the bedrock index. The "A" series maps were produced from 1909 to 2010 and have been replaced by the CGM (Canadian Geoscience Maps) series. CGM maps began production in 2010 and are still being published. Preliminary maps were published from 1941 to 2021.

The Geological Map of Lower Saxony 1 : 25 000 (GK25) provides information on the distribution, nature and sequence of rocks to a depth of two metres below surface. In the case of solid rocks, conclusions can usually be drawn about the continuation of these rock sequences into greater depths.

In the map image and the associated area descriptions, stratigraphy (ageing) and genesis (type of origin) are displayed and described for each geological unit. Furthermore, the area descriptions contain information on the petrography main mixture and secondary mixture (the nature of the rocks) as well as on the lime and humus content of the individual layers. All units shown and numbered in the map image are abbreviated to the symbol key geology (PREUSS et al. 1991) is explained.

The presentation of the geological facts in the base map is subject to certain rules. Rocks at the surface of the terrain of at least 2 meters thickness are characterized by surface colors, overlapping cases of several layers with beam hatching. Horizontal beam hatchings indicate layer sequences that consist exclusively of loose rocks, diagonally arranged beam hatchings refer to loose rock layers over solid rocks. Wide hatches refer to the rocks on the surface of the terrain; underlying layers are characterized by a thinner hatching. Surface colors as well as colors of the hatchings characterize the respective rock type. In order to clarify the natural geological conditions, the original distribution of the rocks is shown in areas with intensive development, although this may be changed by anthropogenic measures (e.g. landfilling).

The GK 25 is available in two machining stations with different accuracy: either as a detailed map (special map) or as an overview map (manuscript map).

The overview maps on a scale of 1: 25 000 (sheet section of TK25) were allocated for the preparation of the Geological Overview Map 1 : 200 000 (GÜK 200) and are already largely generalized for the target scale of the GÜK 200. The processing was carried out with relatively little time (usually a few weeks to months), so that the surface resolution is rather low.

As a rule, the individual GK25s are not compared with the neighbouring leaves at the edge of the leaf. This can lead to so-called "leaf edge faults". The main reasons for this are the different times at which the individual geological maps were created (e.g. a sheet in 1929, the neighboring sheet only in 1985) and that detailed and overview maps are located on neighboring leaf areas, so that no comparison at the leaf edge is possible due to the different processing intensity.

A revision of all geological maps is currently not possible for this scale level.

Database GeoCR25 is a unique geographical information system developed by the on-going digitization of the geological maps at a scale of 1 : 25,000. It also contains database of the reference points and database of the unified geological legend.

The map title is Rock Types. Map scale. North arrow pointing to the north. Map projection is Hammer-Aitoff. Border of Canada. Great Lakes Border for each theme category within Canada. Neat line around the map. Each theme category is identified by a number that corresponds to the legend. Legend is divided into three categories: Metamorphic rocks, Deformed Sedimentary and Igneous rocks, Flat Lying Sedimentary rocks. Tactile maps are designed with Braille, large text, and raised features for visually impaired and low vision users. The Tactile Maps of Canada collection includes: (a) Maps for Education: tactile maps showing the general geography of Canada, including the Tactile Atlas of Canada (maps of the provinces and territories showing political boundaries, lakes, rivers and major cities), and the Thematic Tactile Atlas of Canada (maps showing climatic regions, relief, forest types, physiographic regions, rock types, soil types, and vegetation). (b) Maps for Mobility: to help visually impaired persons navigate spaces and routes in major cities by providing information about streets, buildings and other features of a travel route in the downtown area of a city. (c) Maps for Transportation and Tourism: to assist visually impaired persons in planning travel to new destinations in Canada, showing how to get to a city, and streets in the downtown area.

This U.S. Geological Survey (USGS) data release provides a digital geospatial database for the geologic map of Precambrian metasedimentary rocks of the Medicine Bow Mountains, Albany and Carbon Counties, Wyoming (Houston and Karlstrom, 1992). Attribute tables and geospatial features (points, lines and polygons) conform to the Geologic Map Schema (GeMS, 2020) and represent the geologic map plates as published at a scale of 1:50,000. The 358,697-acre map area includes the geologically complex Medicine Bow Mountains located 30 miles (48 kilometers) west of Laramie in southeastern Wyoming.

These data present geologic map units for the United States (Horton and others, 2017; Wilson and others, 2015) and Australia (Raymond and others, 2012) reclassified to 31 generalized sub-type lithologic groups of igneous, metamorphic, and sedimentary rocks (Lawley and others, 2022). These generalized classifications are based on interpretation of map unit descriptions in the different map compilations. Given that map unit descriptions often contain multiple rock types, there were subjective calls necessary when assigning generalized lithologic classification. The data were developed as part of the tri-national Critical Minerals Mapping Initiative (Kelley, 2020) between the United States, Canada, and Australia, an effort to model and map prospectivity for basin-hosted Pb-Zn mineralization. A national-scale geologic map compilation for Canada is not publicly available. Therefore, Lawley and others (2021) compiled geologic source maps to produce a gridded model layer that is provided ...

The geologic map database of the Great Smoky Mountains National Park region of Tennessee and North Carolina is a result from studies from 1993 to 2003 as part of a cooperative investigation by the U.S. Geological Survey with the National Park Service (NPS). This work resulted in a 1:100,000-scale geologic map derived from mapping that was conducted at scales of 1:24,000 and 1:62,500. The geologic data are intended to support cooperative investigations with the NPS, the development of a new soil map by the Natural Resources Conservation Service, and the All Taxa Biodiversity Inventory. In response to a request by the NPS, we mapped previously unstudied areas, revised the geology where problems existed, and developed a map database for use in interdisciplinary research, land management, and interpretive programs for park visitors.

Bedrock is the solid rock at or below the land surface. Over much of Ireland, the bedrock is covered by materials such as soil and gravel. The Bedrock map shows what the land surface of Ireland would be made up of if these materials were removed. As the bedrock is commonly covered, bedrock maps are an interpretation of the available data. The faults show the details of the structural geology. Faults are the result of great pressure being applied to rock across a whole continent or more. These rocks will break under the pressure, forming faults. Faults are recorded as lines where the break in the rock meets the surface. Geologists map and record information on the composition and structure of rock outcrops (rock which can be seen on the land surface) and boreholes (a deep narrow round hole drilled in the ground). Areas are drawn on a map to show the distribution of rocks. Lines are drawn on a map to show the faults. To produce this dataset, the Geological Survey Ireland (GSI) bedrock geology 1:500,000 and 1:100,000 maps were generalised. The Northern Irish data was generalised using the Geological Survey of Northern Ireland (GSNI) 1:250,000 bedrock geology map. This Bedrock map is best displayed to the scale 1:1,000,000 (1cm on the map relates to a distance of 10km). It is a vector dataset. Vector data portray the world using points, lines, and polygons (areas).The bedrock data is shown as polygons. Each polygon holds information on the rock unit name, age and there is a link to download a pdf of the age description. The faults data is shown as lines. Each line holds information on the fault name if one exists.

As part of the NSTA’s published 2017/18 Activity Plan, the NSTA is publishing a set of regional geological maps for the Central North Sea and Moray Firth areas of the UKCS. These maps represent the first set of deliverables from a 3 year contract with Lloyd’s Register (LR) to produce a series of maps and associated databases for the whole of the UKCS. All data released with this set of geological maps is public domain data. The project has, however, benefited from a number of additional third party data sources which have been used to help inform final maps and/or derive interpreted products. These include the 21st Century Roadmap Palaeozoic project(which is now available in the public domain), PGS’s North Sea Digital Atlas, research data from the University of Aberdeen, CGG’s Target database and relevant products available via the BGS’s Offshore Geoindex. TGS are gratefully acknowledged for providing joined digital log data from LogLinePlus to enable the production of sand flag curves. Schlumberger, TGS and BP are acknowledged for providing additional seismic data to help QC interpretation carried out within the project and CDA are also kindly acknowledged for their support in downloading and providing much of the released well data to LR as part of this project. Due to the high level, regional nature of the project, the maps are being produced for the main geological time intervals e.g. Paleocene, Lower Cretaceous, Upper Jurassic. Each time interval includes the following products:

Depth structure maps Isochore maps Subcrop & supercrop maps Structural elements maps Depositional facies maps Reservoir distribution maps Source rock maps Well penetration maps Hydrocarbon occurrence maps

The products published here include:

a series of layered PDF documents which provide explanations of the various maps and datasets that have been produced plus a set of stratigraphic and petroleum systems charts. an ArcGIS project containing all of the maps and associated data. NSTA web feature services (WFSs) have been included in the map document in this delivery. They replace the use of a shapefile or feature class to represent block, licence and quadrant data. By using a WFS, the data is automatically updated when it becomes available via the NSTA digital copies of the sand flags (.las format) digital copies of the depth and thickness grids produced in the project (.xyz format)
