Area of coal-bearing Mesaverde Formation and Mesaverde Group, southern Piceance Basin assessment area, Colorado (psmvbndg)

This is a shape file and coverage of the top of the Rollins
Sandstone Member. It outlines the area underlain by the
coal-bearing Cameo/Fairfield coal group in the southern
Piceance Basin coal assessment area. Also, it delimits the
area within which resources were calculated and reported in
the southern Piceance Basin coal assessment area. The
polygon was adjusted to match the topography of the DEM.

本数据集为罗林斯砂岩段（Rollins Sandstone Member）顶部的形状文件与覆盖范围数据。该数据勾勒出皮斯安斯盆地（Piceance Basin）南部煤炭评价区内，以含煤卡米奥/费尔菲尔德煤群为下伏地层的区域范围。同时，它划定了皮斯安斯盆地南部煤炭评价区内开展煤炭资源量计算并提交成果报告的区域边界。本次制图所采用的多边形已完成调整，以匹配数字高程模型（Digital Elevation Model, DEM）的地形特征。
