Geologic Provinces of the Far East, 2000 (prv3al)

This coverage includes arcs, polygons and polygon labels that describe U.S. Geological Survey defined geologic provinces of the Far East (China, Mongolia, North and South Korea, Japan, Taiwan, and parts of Cambodia, Thailand and Vietnam). Each province has a set of geologic characteristics distinguishing it from surrounding provinces. These characteristics may include the dominant lithologies, the age of the strata, and the structural style. Some provinces include multiple genetically-related basins. Offshore province boundaries are defined by the 2000 meter bathymetric contour.

本数据集覆盖范围包含弧段、多边形及多边形标签，用于描述由美国地质调查局（U.S. Geological Survey）划定的远东地区地质大区（geologic provinces），覆盖区域包括中国、蒙古国、朝鲜与韩国、日本、中国台湾地区，以及柬埔寨、泰国和越南的部分区域。每个地质大区均具备一套区别于周边大区的独特地质特征，此类特征可涵盖优势岩性、地层时代与构造样式。部分地质大区包含多个成因关联的盆地；近海地质大区的边界以2000米水深等值线划定。
