National Assessment of Oil and Gas Project - Powder River Basin Province (033) Structural Features

This dataset represents lineaments in the Powder River Basin as identified in the following publication: 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. Structural 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). Structural may: 1) enhance secondary reservoir permeability and 2) provide migration pathways in unconventional rocks.
