The difference between basalt and limestone
Limestone is the main raw material for firing lime and cement, which is the flux of iron and steelmaking.
There are biochemical effects generated by the eye, often rich in organic debris. Limestone generally contain some dolomite and clay minerals, when the clay mineral content of 25% to 50%, known as the mudstone. Dolomite content of 25% ~ 50%, known as dolomitic limestone.
Limestone distribution is quite extensive, lithology uniform, easy to mining processing, is a very versatile building stone.
Limestone is mainly formed in the shallow sea environment.Stable limestone can be divided into granite limestone (water transport, sediment formation); biological skeleton limestone and chemical, biochemical limestone. According to the structure can be subdivided into bamboo leaf limestone Limestone, lumps limestone, etc. The main chemical composition of limestone is CaEO3 easy to dissolve, so in the limestone area to form stone and cave, known as the karst terrain
Basalt is the main component of silica, aluminum oxide, iron oxide, calcium oxide, magnesium oxide (and a small amount of potassium oxide, sodium oxide), which contains the largest silica, accounting for about 45 percent to About fifty
Basalts are mostly black, dark brown or dark green, and because of their dense texture, the proportion of granite, limestone, sandstone and shale is heavy, but some basalts are much more , Even in the water can float up.Therefore, this kind of porous body light basalt, called "pumice".
