Decomposed granite of silica sand, silt particles, and clay. Different specific granite types have differing propensities to weather, and so differing likelihoods of producing decomposed granite. The parent granite material is a common type of igneous rock that is granular, with its grains large enough to be distinguished with the unaided eye (i.e., it is phaneritic in texture); it is composed of plagioclase feldspar, orthoclase feldspar, quartz, mica, and possibly other minerals. The chemical transformation of feldspar, one of the primary constituents of granite, into the clay mineral kaolin is one of the important weathering processes. The presence of clay allows water

The Granite bowl's score board is the same scoreboard that the University of Georgia used in Sanford Stadium. It was the scoreboard that was used before the stadium was enclosed and renovated. This scoreboard is also the same one that was used during Georgia's 1980 national championship season. One of the many traditions involved with the Granite Bowl Stadium is touching the spirit rock atop the closed end of the stadium before each game. Hudson Cone, a spokesman for the Granite Association, states that the rock is
