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.
