The resulting granite will likely have been made primarily from quartz, different feldspars, and biotite, however, it can also have a variety of other minerals and oxides present. Quartz content can range from 10-60%, while the feldspar content typically ranges from 65-95%, and biotite content is around 10-15% in most granite.
Igneous rocks like basalt and granite have the highest mineral content, with basalt providing a greater balance of nutrients for optimal plant health and vitality. Created through the cooling and solidification of magma and lava, basalt is the rock material that makes up most of the soils around the world.

As for decomposed granite soil's compaction properties, as with other soils, when compaction energy increases, its maximum dry density increases while its optimum moisture content (OMC) decreases. Among decomposed granite soil's characteristics, one of the differences from other soils is particle crushing. Particle crushing refers to
Completely Decomposed Granite (CDG) is one of the most typical soils found in Hong Kong. However, limited attention has been given on the effect of fines content on its engineering properties. A series of laboratory tests was conducted to examine the effect of fines content, varying from 0 - 20%, on the engineering properties of CDG.

of course, mean a water content of less than0.5/6. He suggested (p. 302) that with crystallization of anhydrous phases dnd consequent accumu-lation of water, the water content may rise to a maximum of 4 or 5/6. For magma with the composition of granite the estimate is less than 1/6 of volatiles (p.296).
