Trachyte is a slightly alkali intermediate volcanic rock. The bulk rock contains approximately 9% alkaline material (K2O+Na2O). The composition is equivalent to that of intrusive syenite. Some alkali feldspar, plagioclase and small amounts of biotite and hornblende appear as phenocrysts. The volcanic relics in the Fushan Mountain National Geopark in Zonhyang, Anhui Province, and in the Xiqiao Mountain National Geopark in Guangdong Province mainly consist of trachyte.
