U-Pb and Lu-Hf isotope, age, and trace element data from zircon separates from the Tanacross D-1, and parts of D-2, C-1, and C-2 quadrangles

This Alaska Division of Geological & Geophysical Surveys (DGGS) Raw Data File presents U-Pb geochronology, Lu-Hf isotopic compositions, and trace-element composition of zircons from six metaigneous and igneous rocks sampled during investigations by DGGS geologists in the northeastern Tanacross quadrangle. The purpose of the Lu-Hf and U-Pb isotopic study is to better understand the Devonian-to-Mississippian and Mesozoic-to-early Paleogene episodes of magmatic and tectonic evolution of the Yukon-Tanana Uplands and the significance of magmatism to the formation of metallic mineral deposits. Products included in this data release are: A summary of sample collection methods, the laboratory report, analytical data tables, and associated metadata. All files are available from the DGGS website: http://doi.org/10.14509/30198.
