The western outer granodiorite of the Tuolumne Intrusive Suite intruded a variety of metasedimentary wall rocks at 93.1 +/- 0.1 Ma. The May Lake metamorphic screen (4500 x 550 m) is a remnant of the chemically diverse metasedimentary host rocks. Their chemical contrast with the invading pluton provides an excellent location to study pluton/wall rock interactions.2) were established for detailed mapping of xenoliths in the granodiorite: one inside a particularly xenolith-rich horizon, and the other in an area with a typically low density of xenoliths. A Nikon total station was used to map the location of allanbsp;...
