Around the plutons of the batholith, the older rocks recrystallized. In other literature, batholith and pluton have been used interchangeably. The Agno quartz diorite batholith is further east near Binga Dam. The granite Aleutian Range batholith has intruded through these rocks. If the pluton is large, it may be called a "batholith" or a "stock". In addition there are many older terranes between the batholith and basalt flows. Geologically the mountain is a granite batholith in a north-south oriented mountain range. The geothermal reservoir is basically a Quaternary basin underlaid by a large granite batholith. A feature of the granites of the batholith is the high concentrations of volatile components. The body of this batholith has been deeply cut by glacial cirques and canyons. The granite batholith is cut by dikes; however, these are uncommon. The rocks consists of small-grained granite which is part of the larger Cornubian batholith. Xenoliths from the Patagonian batholith are also found. There are several contributors to the uplift of the Sierra Nevada Batholith. Over hundreds of millions of years, rocks that were once covering this batholith eroded away.
