Geochemical analyses of surface water, groundwater and springs surrounding Mount Emmons near Crested Butte, Colorado (ver. 2.0, September 2020)
The U.S. Geological Survey (USGS), Colorado Division of Reclamation, Mining and Safety (DRMS), and Coal Creek Watershed Coalition (CCWC) working independently, have intermittently collected samples of surface- and groundwater and springs around Mount Emmons, near Crested Butte, Colorado. This data r
U-Pb zircon data for: The Poncha Pass and Deadman Creek areas, northern Sangre de Cristo Mountains of south-central Colorado
Geologic mapping, characterization of geologic structures, and sampling for geochronology was completed in two areas of the northwestern Sangre de Cristo Mountains from 2011 through 2017. This data release provides the raw analytical data, metadata and sample information for 20 zircon U-Pb age analy
U-Pb detrital zircon data for: lower Paleozoic sedimentary rocks near Silverton, CO USA
This Laser ablation ICPMS U-Pb detrital zircon data set supports mapping and stratigraphic interpretations of the Upper Devonian Ignacio Formation in southwestern Colorado (Silverton area). All samples were collected from a measured stratigraphic section called "Sultan Creek South" located at 37.710
