Superstition Mountains

Porphyritic andesite with crystals of plagioclase feldspar. This igneous rock was extruded from ancient volcanoes that formed the Superstition Mountains. It is common in the alluvial areas on the west side of the Superstitions. Some references refer to the alluvial rocks as mostly welded tuff, dacite and decomposed granite.
