Resource Abstract:
- description: This digital map shows bedding attitude data displayed over the geographic extent of rock stratigraphic units
(formations) as compiled by Colton in 1976 (U.S.Geological Survey Map I-855-G) under the Front Range Urban Corridor Geology
Program. Colton used his own mapping and published geologic maps having varied map unit schemes to compile one map with a
uniform classification of geologic units. The resulting published color paper map was intended for planning for use of land
in the Front Range Urban Corridor. In 1997-1999, under the USGS Front Range Infrastructure Resources Project, Colton's
map was digitized to provide data at 1:100,000 scale to address urban growth issues(see cross-reference). In general, the
west part of the map shows a variety of Precambrian igneous and metamorphic rocks, major faults and brecciated zones along
an eastern strip (5-20 km wide) of the Front Range. The eastern and central part of the map (Colorado Piedmont) depicts a
mantle of Quaternary unconsolidated deposits and interspersed Cretaceous or Tertiary-Cretaceous sedimentary rock outcrops.
The Quaternary mantle is comprised of eolian deposits (quartz sand and silt), alluvium (gravel, sand, and silt of variable
composition), colluvium, and few landslides. At the mountain front, north-trending, dipping Paleozoic and Mesozoic sandstone
and shale formations (and sparse limestone) form hogbacks, intervening valleys, and in range-front folds, anticlines, and
fault blocks. Localized dikes and sills of Tertiary rhyodacite and basalt intrude rocks near the range front, mostly in the
Boulder area.; abstract: This digital map shows bedding attitude data displayed over the geographic extent of rock stratigraphic
