Jacobson discusses Catalina Schist

Carl Jacobson describes the finer points of Catalina Schist mineralogy. Most of the clasts in the San Onofre Breccia here at Stop 15 at Dana Point are from the Catalina Schist. The mineral fuchsite was found in the clasts here, and Peter Weigand, Butch Trembly, Syrus Parvizian, Sally McGill, and Marlin Dicky are hoping to learn how to recognize it.
