Stillwater Complex, Montana - Logs of core drilled by AMAX, 1969 to 1977

This dataset includes pdf representations of drill core logs showing associated drill core information, a pdf of the explanation for the lithology and structure sections of the logs, a shapefile of the locations of the drill holes, and sixteen individual .csv files of tabular data that was compiled from hand written drill core logs. The drill core is from the Stillwater Complex, Montana and was drilled from 1969 to 1977. The core was logged from 1979 to 1993. The data in the pdf images and .csv files includes lithologic, structure, core recovery, grain size, chromite, sulfide, copper, and nickel mineralization information. The pdf logs were created using Golden software's Strater 5 drill core visualization software. The pdf images are provided with both a logarithmic (Stillwater AMAX drill logs log scale.pdf) and linear scale (Stillwater AMAX drill logs.pdf).
