Volcanic rock is a porous stone formed after volcanic eruption, which is very precious. When erupting, the ejected magma includes gas slag, solid magma and bright stone. The temperature and pressure dropped rapidly, and chemical and physical changes took place, so the magma became volcanic rocks.

The three major producing areas of volcanic rocks are Yunnan volcanic rocks, wisdom volcanic rocks and Fuji volcanic rocks, among which Yunnan volcanic rocks are produced in Tengchong County, and Tengchong is also the only producing area of volcanic rocks in Yunnan Province, including basalt, olivine basalt and andesite, which is characterized by many pores, light weight and high strength. Intelligence, Fuji volcanic rocks and Yunnan volcanic rocks have similar effects. Volcanic rocks have many uses, including improving the auditory environment and improving the visual environment, and are widely used in the infrastructure construction of roads, bridges, buildings and other occasions.
