This dataset includes photographic images of thin sections made from xenolith samples collected from the Sliderock Mountain and Susie Peak plutons, Montana, along with a shapefile representing the locations of the samples. The plutons are located north of the Stillwater Complex, Montana, which is exposed along the northern side of the Beartooth Mountains in Montana. To the north of the Stillwater Complex, a gravity anomaly is located where Phanerozoic rocks may unconformably overlie the complex. These Phanerozoic rocks are intruded by Cretaceous plutons that have gabbroid inclusions that resemble other metamorphosed rocks of the Stillwater Complex. Samples of the inclusions were collected, and thin sections were...

A mineral resource assessment was performed by the U.S. Geological Survey (USGS) to assess the potential of undiscovered skarn-hosted tungsten resources in the Northern Rocky Mountain region of eastern Idaho and western Montana. This region has seen moderate tungsten trioxide (WO3) production in the past from a variety of mineralization styles including skarn, vein and replacement, and wolframite-quartz veins. The geology of the area is dominated by large plutons of Cretaceous to Tertiary age, emplaced into a belt of sedimentary rock ranging from Mesoproterozoic to Permian age, and affected by tectonism related to the Sevier and later Laramide orogenies. Known tungsten (W) skarn mineral sites are associated with...

This dataset includes photographic images of thin sections of drill core from the Stillwater Complex, Montana, along with a shapefile representing the location of the drill hole. The core was drilled in order to study contact-type copper and nickel sulfide mineralization in the Stillwater Complex. The images of the entire thin section, both in plane- and cross-polarized light, were taken using a high-resolution digital camera on a macro stand. Each zip file, named with the drill hole identification number, contains the images for a single drill hole. In response to file size restrictions, the data were organized into two parts. The "p1" and "p2" folder designations represent parts 1 and 2. The data in each zip file...

The zip file contains shapefiles showing areas of mineral potential for various commodities. The datasets were compiled from previous mineral resource potential reports which covered the SaMiRA project areas. The shapefiles were compiled from datasets which had different data structure schemes and which used two different types of assessment methodology. The BLM used qualitative categorical and others used the USGS quantitative 3-part form of assessment. The original GIS data was re-formatted so that all of the shapefiles had one of two consistent attribute table structures, one for reports that had quantitative data, and one for reports with qualitative data. A general attribute table structure was created which...

This dataset includes photographic images of thin sections created from hand samples and drill core from the Stillwater Complex, Montana, along with a shapefile representing the locations of the underground samples and drill hole collars. The samples were collected and core was drilled in order to define platinum-group element resources associated with the J-M Reef at the Stillwater Mine in the Stillwater Complex. The images of the entire thin section, both in plane- and cross-polarized light, were taken using a high-resolution digital camera on a macro stand. The data in each zip file is organized into a folder containing the 'RAW' unprocessed .CR2 images (when available) and associated .xmp metadata files, and...
