The Wooley Creek batholith and Slinkard pluton are part of a vertically extensive plutonic system exposed by tilting and erosion. In general, the system is upwardly zoned from pyroxene gabbro to biotite + hornblende granite. Compositional variations among the mineral phases, the effects of slow cooling on mineral compositions, relationships of roof-zone dyke rocks to their depth of origin, and the use of mineral equilibria to estimate the intensive variables of crystallization are discussed. -J.A.Z.
