This data release contains a digitized version of the original 1:24,000-scale analog geologic map titled "Geologic map of the Seminoe Dam NE quadrangle, Carbon County, Wyoming," published by the U.S. Geological Survey (USGS) in 1990. The database includes geospatial features (points, lines, and polygons) with matching attribute tables, nonspatial descriptive and reference tables, and ancillary resource files for correct symbolization, in formats that conform to the Geologic Map Schema (GeMS)--a standard format for the digital publication of geologic maps, available at http://ngmdb.usgs.gov/Info/standards/GeMS/.本数据集发布内容包含1990年由美国地质调查局（U.S. Geological Survey，USGS）发布的原版1:24000比例尺模拟地质图——《怀俄明州卡本县塞米诺尔大坝东北幅地质图》的数字化版本。该数据库包含带配套属性表的地理空间要素（点、线、面）、非空间描述性与参考表，以及用于规范符号化表达的辅助资源文件，所有文件均采用符合地质图模式（Geologic Map Schema，缩写GeMS）的格式——该格式为地质图数字化出版的标准格式，相关标准可通过http://ngmdb.usgs.gov/Info/standards/GeMS/ 查询获取。
