Summary

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 [...]

Purpose

The zircon crystallization ages place numerical limits on what time in geologic history the sampled rocks originated. The geochemical data provide quantitative evidence for classifying the rocks and interpreting how they originated. The Rb-Sr isotopic data are useful for interpreting the lithospheric setting (for example, continental or oceanic) in which the sampled rocks originated. The oxygen isotope data (delta 18O) are useful for interpreting the degree to which continent-derived sedimentary material contaminated the parent magmas of the sampled rocks. The dataset can be used for research topics such as the regional geologic history and for applied studies such as resource assessment.
