SHRIMP U-Pb and LA-ICPMS U-Pb geochronologic data for igneous and metasedimentary rocks in central Idaho mineral province, U.S.A.
Description
These data are for a geochronologic study of emplacement ages for plutons of the Cretaceous Idaho batholith and detrital zircon ages for metasedimentary rocks, west-central Idaho. Zircon from six samples of discrete plutons across a regional transect were dated by sensitive high resolution ion microprobe (SHRIMP). SHRIMP U-Pb ages of igneous rocks connect the igneous activity to structural history, crustal depths, and origins of epigenetic gold-silver-antimony-tungsten±mercury mineral deposits. Zircon from four samples of metasedimentary rocks in the southern part of the central Idaho mineral province were dated - three by laser ablation inductively coupled plasma mass spectrometry (LA-ICPMS) methods and one by SHRIMP methods - to provide maximum depositional ages and details about original sedimentary provenances. These SHRIMP and LA-ICPMS U-Pb data are shared to meet open data requirements.
