Data release of geochemistry and geochronology for Proterozoic rocks in southwestern Colorado and rocks from drill core from Colorado, North Dakota, Nevada, Wyoming, Montana, and Nebraska

공공데이터포털

This U.S. Geological Survey (USGS) data release provides whole rock major, minor, and trace element geochemical data, mineral chemistry, and monazite and xenotime geochronology for Proterozoic rocks in the Needle Mountains of southwestern Colorado and for Proterozoic rocks sampled from drill cores from Colorado, North Dakota, Nevada, Wyoming, Montana, and Nebraska. Samples from the Needle Mountains were collected in order to constrain the polyphase tectonic evolution of the area. Additionally, multi-scale compositional mapping, petrologic modeling and in-situ geochronology constrain the pressure-temperature-time paths from basement gneisses and quartzites. Drill core samples are part of a larger characterization of the age and geochemical character of basement terranes in the United States.

Data Release of Geochemical, Geochronologic, and Isotopic Data for Proterozoic rocks from the Mountain Pass REE deposit and its host rocks, Arizona, California, and Nevada

공공데이터포털

This U.S. Geological Survey (USGS) data release includes whole-rock major, trace, and rare earth element geochemical data, whole-rock and mineral Nd-Pb-Sr isotopic data collected by thermal ionization mass spectrometry (TIMS), and uranium-lead isotopic data collected by Sensitive High Resolution Ion Microprobe-Reverse Geometry (SHRIMP-RG) methods that characterize the Mountain Pass Rare Earth Element deposit, associated Mesoproterozoic igneous rocks, and their Paleoproterozoic host rocks in Arizona, California, and Nevada. SHRIMP-RG data were collected between 2013 and 2018. Sample collection and whole-rock geochemistry were carried out between 1981 and 2015.

Zircon U-Pb data for Paleoproterozoic metasedimentary rocks of the Gunnison block, central Colorado, USA

공공데이터포털

This data release includes raw detrital zircon U-Pb data for Paleoproterozoic metasedimentary rocks of the Gunnison block, central Colorado, USA. Detrital zircon U-Pb data for five samples of metasedimentary rock (totaling 1459 zircon U-Pb dates) were acquired via laser ablation-inductively coupled plasma-mass spectrometry (LA-ICP-MS) at the University of Arizona LaserChron Center. The data provide constraints on the sediment provenance, maximum depositional age, and timing of metamorphism of these metasedimentary rocks, providing insights on the crustal and tectonic evolution of the Gunnison block and Yavapai Province.
