Thinning and Heating of Laramide Continental Lower Crust Recorded by Zircon Petrochronology

Thinning and Heating of Laramide Continental Lower Crust Recorded by Zircon Petrochronology

Abstract Zircon grains from the metasedimentary lower crust of the Rio Grande Rift, New Mexico, preserve a metamorphic record of the transition from Laramide compression to Eocene extension. Zircon U‐Pb isotopes and trace‐element concentrations from five two‐pyroxene metaigneous granulite xenoliths...
