GEOLOGIC GUIDE TO STONE MOUNTAIN PARK Georgia

Between 1869 and 1882, the Stone Mountain Granite and Railway Co. made the first effort toward a systematic production of Stone Mountain Granite. In 1882, the Venable Bros. took over the production of the granite and through their efforts, Stone Mountain became one of the largest granite­ producing areas in the nation (Watson, 1902). 1

Which Types of Granite Emit the Most Radon? Sciencing

Granites are rocks that were originally formed at great depths within Earth''s crust from molten magma, but because of subsequent uplift and erosion, granites are now a part of the surface landscape. Minerals, including those containing uranium, were segregated during the final cooling phases of the graniteforming process.

Granite (/ ˈ ɡ r æ n ɪ t /) is a common type of felsic intrusive igneous rock that is granular and phaneritic in texture. Granites can be predominantly white, pink, or gray in color, depending on their mineralogy. The word "granite" comes from the Latin granum, a grain, in reference to the coarsegrained structure of such a holocrystalline

Granite Outcrops New Georgia Encyclopedia

The rock surface is commonly subject to exfoliation, with "shells" of rock sloughing away to create crevices and talus piles at the base. Uneven weathering of the rock surface results in shallow depressions, called weathering or solution pits. It is in these depressions that the most distinctive graniteoutcrop plants and animals occur.

Heat production in granitic rocks: Global analysis based

The analysis of the relationship between heat production in the granitic rocks and the tectonic environment where the granitic rocks were formed shows that the age of granites is more important than the granitetype in controlling bulk rock heat production (Table 10, Fig. 10). For Phanerozoic granites, we do not find any correlation between the
