Basalt is a kind of basal spray rock, its chemical composition is similar to FAI long Rock or diabase, SiO2 content changes between 45%~52%, K2O+NA2O content is slightly higher than intrusive rock, CaO, Fe2o3+feo, MgO content is slightly lower than intrusive rock. The mineral composition mainly consists of the base long Shi stone, the secondary minerals have olivine, hornblende and Black mica, and so on, the rocks are dark color, generally is dark, sometimes gray green and dark purple and so on. It is a plaque-like structure.

Stomatal tectonics and almond structure are common. The density of the basalt is 2.8~3.3g/cm3, the compressive strength of the dense is very high, it can be up to 300MPa, sometimes higher, and the strength decreases when there is glass and pores. Basalt durability is very high, joints are many, and the joint surface is more pentagon or hexagonal, forming a column joint.
