Tabular geochronologic, geochemical, and isotopic data from igneous rocks in the Lane Mountain area, San Bernardino County, California
June 12, 2023
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 samples, 6 Late Jurassic samples, and 2 Late Cretaceous samples. The dataset consists of six tables in csv (comma separated values) format: (1) sample localities and lithology; (2) SHRIMP-RG (Sensitive High-Resolution Ion Microprobe-Reverse Geometry) U-Pb zircon geochronologic data; (3) sample ages derived from the geochronologic data; (4) whole-rock geochemical data determined by ICP-AES-MS (Inductively Coupled Plasma Atomic Emission Spectroscopy-Mass Spectrometry) and WDXRF (Wavelength Dispersive X-ray Fluorescence); (5) whole-rock Rb-Sr isotopic data measured on a solid source mass spectrometer, along with calculations of the original 87Sr/86Sr isotopic ratios based on the measured data; and (6) whole-rock oxygen isotope determinations of delta 18O.

The Eastern California Shear Zone (ECSZ) Mapping project, funded by the National Cooperative Geologic Mapping Program, combines surficial and bedrock geologic mapping, geophysical surveys, and high-resolution topographic data analysis with neotectonic, geomorphic, structural, volcanic, and geochronologic studies to better understand the tectonic framework and landscape evolution of the ECSZ in the...
Geochronologic, isotopic, and geochemical data from pre-Cretaceous plutonic rocks in the Lane Mountain area, San Bernardino County, California
Pre-Cretaceous, predominantly dioritic plutonic rocks in the Lane Mountain area, California, intrude metasedimentary and metavolcanic rocks considered part of the El Paso terrane. New geochronologic (uranium-lead zircon), geochemical, and isotopic data provide a reliable basis for dividing these pre-Cretaceous plutonic rocks into two mappable suites of Permian–Triassic and Late Jurassic...
