Cassiterite (SnO2), a main ore mineral in tin deposits, was collected by multiple Russian geologists or obtained from museum collections in both the USA and Russia and dated at the U.S. Geological Survey. The dated samples represent four different mining districts spanning the entire country from the village of Pitkäranta in the west (31° E Longitude) to the Merekskoe Deposit in the Russian Far East (134°E Longitude). The samples were recovered from a variety of host deposit types that range from the Proterozoic to Phanerozoic. Cassiterite (in the form of mounted loose grains) was prepared and analyzed for direct age dating on a laser ablation inductively coupled plasma mass spectrometer (LA-ICP-MS) system at the...

This U.S. Geological Survey (USGS) data release includes whole rock geochemical and isotopic data, and uranium-lead isotopic data collected by both Laser Ablation Inductively Coupled Plasma Mass Spectrometry (LA-ICP-MS) and Sensitive High Resolution Ion Microprobe-Reverse Geometry (SHRIMP-RG) methods for rocks in Colorado, Wyoming, Utah, and New Mexico.

This dataset accompanies planned publication 'Paleogene mid-crustal intrusions in the Ruby Mountains Metamorphic Core Complex, northeastern Nevada' [IP-153033], to be published in Geosphere, as well as planned future publications in this region. The data encompass U-Pb zircon age and trace element data and whole-rock Pb, Sr, and Nd isotopic data from igneous and metamorphic rocks throughout the Ruby Mountains, East Humboldt Range, Lizzies Basin, Lamoille Canyon, and Angel Lake areas of northeast, Nevada. Samples were collected from this area by Allen McGrew (Univ. of Dayton), Arthur Snoke (Univ. of Wyoming), Wayne Premo (USGS) and Keith Howard (USGS), who brought them to the USGS Denver for analysis. The analyses...

These data consist of sulfur and carbon isotope compositions, concentrations of selected elements, and concentrations of pyrite sulfur and organic carbon in mudstone samples collected from five cores drilled in the Howards Pass district, Yukon-Northwest Territories, Canada. The cores were drilled between 2006 and 2014, site visits and core sampling took place between 2009 and 2016, and laboratory work was conducted between 2011 and 2017. The data were obtained as part of a research project described in the following publication: Johnson, Craig A., Slack John F., Dumoulin, Julie A., Kelley, Karen D., and Falck, Hendrick, 2018, Sulfur isotopes of host strata for Howards Pass (Yukon-Northwest Territories) Zn-Pb deposits...

Cassiterite (SnO2) samples were collected from alluvial ore concentrate from the Abu Dabbab Granite in eastern Egypt. Samples (in the form of mounted loose grains) were prepared and analyzed for direct age dating on a laser ablation inductively coupled plasma mass spectrometer (LA-ICPMS) system at the U.S. Geological Survey in Denver, Colorado in February 2019. This data release accompanies the publication, 'Monazite and cassiterite U-Pb dating of the Abu Dabbab rare-metal granite, Egypt: Late Cryogenian metalliferous granite magmatism in the Arabian-Nubian Shield.' (Lehmann and others, 2020). The publication constrains the timing of the magmatic-hydrothermal processes of the Abu Dabbab Granite which represents...
