Description

This dataset represents lineaments in the Powder River Basin as identified in the following U.S. Geological Survey Professional Paper: Anna, L.O., 1986, Geologic framework of the ground water system in Jurassic and Cretaceous rocks on the Northern Great Plains, in parts of Montana, North Dakota, South Dakota, and Wyoming: U.S. Geological Survey Professional Paper 1402-B, 36 p. A lineament is defined as a linear topographic feature of regional extent that is believed to reflect crustal structure (Hobbs et al., 1976, p. 267). Lineament features were transferred from the publication to a hard-copy base map by province geologist, then digitized and referenced for use in a Geographic Information System (GIS). Lineaments may: 1) enhance secondary reservoir permeability and 2) provide migration pathways in unconventional rocks.
