- Description:
- Abstract: Geochemical data presented in this report pertain to Cretaceous
- igneous intrusions of the Boulder batholith and its satellitic plutons in
- southwest Montana. The geographic area addressed in this compilation is
- approximately bounded by latitudes 45.6 and 46.7 degrees North and
- longitudes 112.75 and 111.5 degrees West. These data were compiled in
- order to establish the geologic framework for world-class mineral deposits
- of the Butte district. Although these deposits and their host rocks have
- been the subject of many investigations, the petrologic characteristics of
- associated intrusive rocks have not been systematically compiled,
- synthesized, or interpreted. Abundant late Mesozoic intrusions in the
- study area are probably byproducts of subduction-related processes,
- including back-arc magmatism that prevailed along the west edge of the
- North American plate during this interval. The ultimate goal of this
- effort will be an evaluation of the time-space-compositional evolution of
- Mesozoic magmatism associated with the Boulder batholith and
- identification of genetic associations between magmatic and mineralizing
- processes in this region.
- Purpose: This product is a compilation of geochemical information for
- intrusions of the Boulder batholith and is intended to aid in the study of
- the geology and metallogenesis of the region.

-
- Native_Data_Set_Environment: Microsoft Windows XP Version 5.1 (Build 2600)
- Service Pack 2; ESRI ArcCatalog 9.3.1.1850
-
- Data_Quality_Information:
- Logical_Consistency_Report: Map elements were visually checked for overshoots,
- undershoots, duplicate features, polygon closure, and other errors by the
- author and by the GIS technician that created the digital database.
- Automated routines were also used to check the databases for polygon label
- errors, line or point attribution errors, sliver polygons, dangling arcs,
- intersection errors, and projection information. Check plots of the map
- were reviewed by for consistency with basic geologic principles and general
- conformity to USGS mapping standards.
-
- Completeness_Report: Data are complete. All geospatial database elements are
- attributed.

- Process_Step:
- Process_Description: Paul Denning scanned the original, stable-base copy
- of the 1988 geologic map (Smedes and others, 1988) and exported the
- resulting data to ArcMap where polygons were cleaned up and attributed.
- The resulting digital geologic map is intended to be a faithful
- representation of the original map. The ArcMap data were exported to
- Adobe Illustrator to create the PDF version of the geologic map.
- Locations for all samples for which geochemical data were compiled were
- added to the PDF version of the geologic map by Ed du Bray. More
- details of the geochemical data compilation process are provided in the
- accompanying text, DS454.pdf
