Stillwater Complex Strike and Dip Database (Under Revision) Note: this data release is currently being revised and is temporarily unavailable. This file includes strike and dip information for the area of the Stillwater Complex, located in southwestern Montana. This dataset was created from pre-existing digital strike and dip information and from digitizing strike and dip locations from georeferenced map images. The data includes information about the strike and dip locations; the geologic unit and rock type the measurement was taken on; information about the source map, such as map title and scale; and other miscellaneous information.

Data were acquired by Xcalibur Multiphysics (Canada), Ltd. with three different airborne sensors: the 30Hz TEMPEST time-domain AEM instrument that is used to map subsurface geologic structure at depths up to 300 meters (m) depending on the subsurface resistivity; a Scintrex CS-3 cesium vapor magnetometer that detects changes in deep (hundreds of meters to kilometers) geologic structure based on variations in the magnetic properties of different formations; and a Radiation Solutions...
