玄武岩是一种岩浆在高温高压下从地慢、地壳喷出地表溢流凝固而形成的岩石，广泛分布于世界各地。我国各省（区、市）几乎都有分布，资源极为丰富，但对它的开发利用程度却非常低，大量的碎料、块石、边角料堆积如山，占用了大量的土地，而用其作石材、混合材用量又极为有限。 Basalt is a kind of rock which is formed by overflow and solidification of the magma at high temperature and high pressure, slowly spreading from the earth to the earth surface, and widely distributed in all parts of the world. There are almost all provinces (autonomous regions and municipalities) in our country with extremely rich resources, but their development and utilization are very low. A lot of debris, blocks and scrap are accumulated in mountains and occupy a large amount of land, , The amount of mixed materials and very limited.
