Faults - Platte River Basin (2013)

A primary goal of this work is to develop geologic map datasets with standardized structure and attribution. The database design and standards are documented in Chapter A of this series. The intent is that contiguous databases can be merged seamlessly and without any additional effort. In addition to a common database structure, the conterminous U.S. state databases (the contiguous 48 states) have been fitted to a set of standard state boundaries so that, when states are merged, they match without slivers or overlap. No attempt has been made to reconcile differences in mapping across state boundaries. Changed a normal fault to a thrust fault, based on a more detailed map that can be found at this reference: Lillegraven, J.A., and Snoke, A.W., 1996, A new look at the Laramide Orogeny in the Seminoe and Shirley Mountains, Freezeout Hills, and Hanna Basin, south-central Wyoming: Wyoming State Geological Survey Public Information Circular No. 36, 52p.
