Isotopic ages of rocks in the northern Front Range, Colorado Isotopic ages of rocks in the northern Front Range, Colorado
These maps, and the tables that accompany them, are a compilation of isotopic age determinations of rocks and minerals in four 1:100,000 quadrangles in the northern and central Front Range, Colorado. Phanerozoic (primarily Tertiary and Cretaceous) age data are shown on one map; Proterozoic data are on the other. A sample location map is included for ease of matching specific localities...

Locatable mineral reports for Colorado, South Dakota, and Wyoming provided to the U.S.D.A. Forest Service in fiscal years 2003-2005 Locatable mineral reports for Colorado, South Dakota, and Wyoming provided to the U.S.D.A. Forest Service in fiscal years 2003-2005
Introduction: The U.S. Geological Survey is required by Congress (under Public Law 86-509) to provide Locatable Mineral Reports to the U.S.D.A. Forest Service whenever National Forest System lands are sold or exchanged. This volume is a compilation of the reports already provided to the Forest Service by the author in fiscal years 2003-2005 (October 2002 - September 2005). Altogether...

Preliminary integrated geologic map databases for the United States: Central states: Montana, Wyoming, Colorado, New Mexico, North Dakota, South Dakota, Nebraska, Kansas, Oklahoma, Texas, Iowa, Missouri, Arkansas, and Louisiana Preliminary integrated geologic map databases for the United States: Central states: Montana, Wyoming, Colorado, New Mexico, North Dakota, South Dakota, Nebraska, Kansas, Oklahoma, Texas, Iowa, Missouri, Arkansas, and Louisiana
The growth in the use of Geographic Information Systems (GIS) has highlighted the need for regional and national digital geologic maps attributed with age and lithology information. Such maps can be conveniently used to generate derivative maps for purposes including mineral-resource assessment, metallogenic studies, tectonic studies, and environmental research. This Open-File Report is...
