Abstract

The Wooley Creek batholith, Slinkard pluton, and associated hypabyssal intrusive rocks constitute a large-volume, Middle Jurassic (approx 162 Ma) magmatic system in the north-central Klamath Mountains of California. Tilting and erosion subsequent to Nevadan thrusting exposed a structural section at least 9 km thick. The system is heterogeneous with reference to initial 87 Sr/ 86 Sr (Sr i ) and delta 18 O, including mafic selvages and mafic dikes that intrude the Wooley Creek batholith and its roof rocks. Isotopic data are presented. -from Authors
