Abstract:
This data set includes a GIS geologic map database of an Early
Proterozoic metavolcanic and metasedimentary terrane
extensively intruded by Early and Middle Proterozoic granitic
plutons. Laramide to Tertiary deformation and intrusion of
felsic plutons have created numerous small mineral deposits
that are described in the tables and are shown on the figures
in the accompanying text pamphlet. Also included in the
pamphlet are numerous chemical analyses of igneous and meta-
igneous bodies of all ages in tables and in summary geochemical
diagrams. The text pamphlet also contains a detailed
description of map units and discussions of the aeromagnetic
survey, igneous and metmorphic rocks, and mineral deposits. The
printed map sheet and browse graphic pdf file include the
aeromagnetic map of the study area, as well as figures and
photographs.
Purpose:
This GIS geologic map database is provided to facilitate the
presentation and analysis of earth-science data for this region
of Colorado. This digital map database may be displayed at any
scale or projection. However, the geologic data in this
coverage are not intended for use at a scale other than 1:30,
000. Supplemental useful data accompanying the database are
extensive geochemical and mineral deposits data, as well as an
aeromagnetic map.
