This dataset provides geochronologic and geochemical data for selected metasedimentary and associated rock samples collected in the Lane Mountain area about 20 kilometers northeast of Barstow, California. Geochronologic data were obtained for 24 samples, and geochemical data were obtained for 5 of these. The dataset consists of four tables in csv (comma separated values) format: (1) sample localities and lithology; (2) LA-SF-ICPMS (Laser Ablation Sector Field Inductively Coupled Plasma Mass Spectrometry) U-Pb (uranium-lead) zircon geochronologic data; (3) SHRIMP-RG (Sensitive High-Resolution Ion Microprobe-Reverse Geometry) U-Pb zircon geochronologic data; and (4) whole-rock geochemical data determined by ICP-AES-MS...

This Geologic Map Schema (GeMS) database contains all the geologic map information used to publish the Preliminary Bedrock Geologic Map of the Blythe 30' x 60' Quadrangle, California and Arizona, U.S. Geological Survey Open-File Report 2021-1097. The Blythe 30' x 60' quadrangle in southeastern California and southwestern Arizona displays complex geology that includes Mesozoic contractional deformation, metamorphism, and magmatism and Cenozoic extensional deformation and magmatism. The scope of the present map is limited to bedrock units of Miocene and older age because the younger deposits have not been mapped in sufficient detail across the quadrangle to support a systematic compilation. This geologic map database...

This dataset provides geochronologic, geochemical, and isotopic data for selected igneous rock samples collected in the Lane Mountain area about 20 kilometers northeast of Barstow, California. Uranium-lead (U-Pb) zircon geochronologic and whole-rock geochemical data were obtained for 62 samples of which 28 are from Permian to Triassic plutonic rocks and dikes, 24 are from Late Jurassic plutonic rocks, 6 are from Late Cretaceous plutonic rocks and dikes, and 4 are from Miocene volcanic rocks, Rubidium-strontium (Rb-Sr) isotopic data were obtained for 8 of the Permian to Triassic samples, 9 of the Late Jurassic samples, and 4 of the Late Cretaceous samples. Oxygen isotope data were obtained for 2 Permian to Triassic...
