Digital database of the previously published map showing geology, structure, and oil and gas fields in the Sterling 1 degree x 2 degrees quadrangle, Colorado, Nebraska, and Kansas

This release contains geospatial data digitized from the Map Showing Geology, Structure, and Oil and Gas Fields in the Sterling 1x2 Degree Quadrangle, Colorado, Nebraska, and Kansas (Scott, 1978) and was compiled as part of the National Geologic Synthesis project. The geospatial data depicts the geology of this quadrangle, which is dominated by Quaternary alluvial and aeolian deposits overlying Tertiary and Cretaceous sedimentary rock, including the Ogallala formation, the Fox Hills sandstone, and the Pierre shale. The included database includes spatial data depicting the locations of mapped geologic contacts and faults, polygons denoting the mapped surficial extent of geologic formations, and structural contours denoting the depth [...]

本数据集包含从《科罗拉多州、内布拉斯加州与堪萨斯州斯特林1×2度制图幅地质、构造及油气田图》（Scott，1978）数字化而来的地理空间数据（geospatial data），该数据系作为国家地质综合项目（National Geologic Synthesis project）的组成部分编制而成。该地理空间数据刻画了本制图幅的地质特征，其地层主体为覆于第三纪（Tertiary）及白垩纪（Cretaceous）沉积岩之上的第四纪（Quaternary）冲积与风成沉积物，涵盖奥加拉拉组（Ogallala Formation）、福克斯希尔砂岩（Fox Hills Sandstone）以及皮埃尔页岩（Pierre Shale）。本数据集附带的数据库包含三类空间数据：已填绘的地质接触带与断层的位置数据、用以表征地质地层地表填绘范围的多边形要素，以及表示深度[...]的构造等值线。
