Decomposed granite is an igneous rock that has been exposed to weather over a long period and been fractured into pieces about ⅜ inches or smaller. It resembles gravel and is usually made from mica, quartz or feldspar. Decomposed granite is a rock of granitic origin that has weathered to the point that it readily fractures into smaller pieces of weak rock. Further weathering produces rock that easily crumbles into mixtures of gravel-sized particles, sand, and silt-sized particles with some clay.
