A map showing the distribution of rocks at Earth's surface.
in this circular, maps that depict the bedrock at or near the earth's surface as if the soils and vegetation were removed.
Graphical, two-dimensional representation of the outcrop patterns of rock units (formations) on the land surface. Typically has topographic information, (such as elevation changes) superimposed on it.
A diagram or drawing on a horizontal plane of part of the earth's surface showing by means of lines, colors, symbols, and orientation thedistribution of selected features such as particular surface or subsurface units of rocks or sediments.
a map of the different types of rocks that are on the surface of the Earth
a two-dimensional graphic representation of selected geologic features on a part of the earth as observed and interpreted by the authors
depicts the age of rocks (ancient, dinosaur age, or mammal age) and under what conditions the rock formed (on land, in the sea, on a volcano)
A geologic map is a map that notes the structure and composition of geologic features, like the presence of minerals, rock types, earthquake faults, underground water, and landslide areas.
A map showing the type and spatial distribution of rocks at the surface of the Earth. Rock formations are color-coded and symbols for geological structures are annotated, so age relationships are evident. Topographic contours and cultural features can also appear on geologic maps.
a map showing geologic information, such as the distribution, nature, and age relationships of rock units, and the occurrence of structural features (folds, faults, joints), mineral deposits, and fossil localities.
a map on which is recorded the distribution, nature, and age relationships of rock units and the occurrence of structural features. AGI
A geologic map is a special-purpose map made to show subsurface geological features. In the United States, geologic maps are usually superimposed over a topographic map (and at times over other base maps) with the addition of a color mask with letter symbols to represent the kind of geologic unit, stratigraphic contour lines, fault lines, strike and dip symbols, and various additional symbols as indicated by the map key.
