... in eastern exposures of the Yerington batholith, Yerington district, Nevada. The phlogopite is preferentially oriented and defines foliation, suggesting that the alteration zone has accommodated structural deformation. The mineral association consists of near-endmember phlogopite with local clusters...

... in solution (see discussion at Stop 8). In numerous porphyry-copper-related skarn deposits, andradite and actinolite are coeval and associated with ore formation taking place at the time of potassic alteration in the porphyry stock ( Atkinson and Einaudi, 1978 ; Einaudi, 1982b ). In the Yerington district...
