Welcome to our directory of 149 Chinese granites. Owing to the large distances involved it may not be economical to process northern Chinese granites in Xiamen however we shall advise this at the time of your enquiry.
A coarse or medium-grained intrusive igneous rock that is rich in quartz and feldspar; it is the most common plutonic rock of the Earth's crust, forming by the cooling of magma (silicate melt) at depth. The principal constituent of granite is feldspar. Both plagioclase feldspar and alkali feldspar are usually abundant in it, and their relative abundance has provided the basis for granite classifications. In most granite, the ratio of the dominant to the subdominant feldspar is less than two. Rocks containing less than 20 percent quartz are almost never named granite, and rocks containing more than 20 percent (by volume) of dark, or ferromagnesian, minerals are also seldom called granite. The minor essential minerals of granite may include muscovite, biotite, amphibole, or pyroxene. Biotite may occur in granite of any type and is usually present, though sometimes in very small amounts.
A rock consisting of equal proportions of orthoclase and plagioclase plus quartz may be considered a quartz monozonite. A granite containing both muscovite and biotite micas is called a binary granite.
Not all granites listed are "true" granites however for commercial purposes they are grouped together. It must be noted that many granites listed here internationally may be nominated as a granite but in the area of application of the European Standard the granite must have its correct petrographical nomination.Do You Have Any Granite Samples To Include?
