Fission Track Data and Ages of Apatite and U-Pb Isotopic Data and Ages of Igneous and Detrital Zircon from Selected Rocks from the Lake Clark and Lake Iliamna Region of South-Central Alaska
This data set contains fission track data and associated ages of apatite from igneous and sedimentary rocks, U-Pb isotopic data and associated ages of zircon from a subset of the igneous rock samples, and U-Pb isotopic data and associated ages of detrital zircon from a subset of the sedimentary rock samples. All samples were collected from the region surrounding Lake Clark and Lake Iliamna in southwestern Alaska. All samples were collected as part of geological mapping and research conducted in 2008 and funded by the U.S. Geological Survey Mineral Resources External Research Program. Apatite and zircon grains were separated and analyzed by Apatite to Zircon, Inc. (A2Z). All analyses were conducted in 2009 using standard fission track dating techniques and laser-ablation-inductively-coupled-plasma-mass spectrometry (LA-ICP-MS) techniques
