Geochemical data for alkaline igneous rock units in the Cripple Creek district, Colorado USA: 1989-2016

New major and trace element geochemical analyses of alkaline igneous rocks in this area. of historic gold mining in order to characterize the tellurium and other trace element constituents of predominantly unaltered rocks genetically associated with mineralization, to help understand the mechanism of enrichment in these deposits. 75 samples were analyzed by a variety of modern techniques and instruments.

Geochronology and correlation of Tertiary volcanic and intrusive rocks in part of the southern Toquima Range, Nye County, Nevada

40Ar/39Ar dating, electron microprobe analyses and geologic mapping help clarify chronology and correlations of the numerous volcanic and intrusive units exposed in the area and interpret the petrogenesis of a few of the volcanic units.

U-Pb zircon data for: Cretaceous plutonic rocks of western Glacier Bay National Park and Preserve

Geochronologic analyses to determine the ages of the plutonic rocks in the Glacier Bay area. Five samples were dated by laser ablation-inductively coupled plasma mass spectrometry U-Pb methods. These analyses contribute to understanding the geologic history of this area. Sample locations and characteristics, along with measured isotopic ratios and calculated ages are provided in CSV format.
