Surficial deposits and materials in the eastern and central UnitedStates (east of 102 degrees west longitude)
The surficial geologic map of the Eastern and Central United Statesdepicts the areal distribution of surficial geologic deposits and othermaterials that accumulated or formed during the past 2+ million years,the period that includes all activities of the human species. Thesematerials are at the surface of the earth. They make up the "ground"on which we walk, the "dirt" in which we dig foundations, and the �soil�in which we grow crops. Most of our human activity is related in oneway or another to these surface materials that are referred tocollectively by many geologists as regolith, the mantle of fragmentaland generally unconsolidated material that overlies the bedrockfoundation of the continent. The map is based...
Clinker in the Rosebud-Robinson coal zone area from 1999 National Coal Resource Assessment (rsclkg.shp )
This ArcView shapefile contains a polygon representation of the clinker in the Colstrip coalfield. This theme was created specifically for the National Coal Resources Assessment in the Northern Rocky Mountains and Great Plains Region.
This ArcView shapefile contains a representation of clinker in the Decker coalfield area. This theme was created specifically for the National Coal Resources Assessment in the Northern Rocky Mountains and Great Plains Region.
Clinker regions found in the Powder River Basin, 1:24000-scale. Clinker is baked and fused geologic material generated during the combustion of a coal seam. Each area is attributed with reference to the name of the coal seam responsible for producing the clinker. The data were originally produced by digitizing photointerpreted clinker polygons off of 1:24,000 USGS quadrangles.
