Geochronology and geochemistry of Paleoproterozoic metamorphic rocks in the Midcontinent
Abstract
We present isotopic and geochemical data for several Archean and Paleoproterozoic metamorphic rocks in the Penokean orogen, USA. These data include new U-Pb and trace element analyses of apatite, titanite, and monazite; bulk rock major and trace element compositions; and whole rock and garnet Lu-Hf and Sm-Nd isotope compositions.
