U-Pb Isotopic Data and Ages of Zircon from the Manzano Mountains, New Mexico
This data set contains tables containing uranium-lead (U-Pb) isotopic data and the crystallization age of zircon from a metamorphic rock from the Manzano Mountains, New Mexico, collected in 2005. The bulk sample was processed into concentrated mineral separates of zircon at the University of Texas at Austin and analyzed by U.S. Geological Survey (USGS) research scientists at the Stanford-USGS Sensitive High Resolution Ion Microprobe with Reverse-Geometry (SHRIMP-RG) at Stanford University. The data table "geochronology_SHRIMP-RG_manzanoMtns_jones.csv" accompanying this data release reports the isotopic composition of uranium (U) and thorium (Th) measured in each grain, ratios of two isotopes of lead (207Pb and 206Pb) and two isotopes of uranium (235U and 238U), the age of each grain, and concentrations of selected trace elements measured in each grain. A second table "geochronology_sampleSummary_manzanoMtns_jones.csv" reports the sample location, rock characteristics, and interpreted age. Additionally, a third data table "geochronology_dataDictionary_manzanoMtns_jones.csv" is provided as a reference guide for the user.
