Best Answer

Decomposed granite is just old granite rock that has weathered into samller particles over millions of years. The particles are like very coarse sand or very tiny gravel. These particles are coming into common use in various landscaping applications. Geologists have more technical names for these materials, but DG is the commonly used term. In California, DG often occurs in places where exposed basoliths have weathered and eroded. Examples in California include parts of the Tahoe basin, Shasta Bolly - Grass Valley Creek watersheds west of Redding, and parts of the mountains to the east of San Diego. DG derived soils are notoriously unstable and subject to very high erosion rates. Examples of erosion control projects related to DG soils can be found at the Trinity Resource Conservation District (Trinity County, Calif., USA) website: http://www.tcrcd.net/pdf/GVC_10-Yr-Planting_Final-Report.pdf and http://www.tcrcd.net/pdf/GVC_Restoration_Manual.pdf
