Geologic map of the Stillwater Complex, Montana: a digital database

This dataset was developed to provide a spatial database of the 1:12,000 scale
geologic map of the Stillwater Complex for use in future spatial analysis.
These data can be printed in a variety of ways to display various geologic
features or used for digital analysis and modeling. This database is not meant
to be used or displayed at any scale larger than 1:12000. The digital geologic
map graphics and plot files (i797.gra/ps and i797-map.pdf) that are provided in
the digital package are representations of the digital database. They are not
designed to be cartographic products.

This report provides a digital version of the Geologic map of the Stillwater
Complex, Montana originally published by N. Page and W. Nokleberg (1974).
Paper copies of the four geologic map sheets from the original report were
scanned and initially attributed by Optronics Specialty Company (Northridge,
CA) and remitted to the U.S. Geological Survey for further attribution and
publication of the geospatial digital files. The resulting digital geologic
dataset can be queried in a geographic information system (GIS) in many ways to
produce a variety of geological maps.

This GIS dataset consists of two Arc/Info datasets. The first is a line and
polygon file (i797) containing geologic contacts and structures (lines) and
geologic map rock units (polygons). A second file contains structural point
data (i797p). Since the topographic base map for the original publication is no
longer readily available, a georeferenced image (tiff) of the original basemap
is also included.
