Jade, beautiful stone also. In a word, there are many kinds of jade, most of them are rocks, and a few are biological and artificial. What is rock? Rocks are a collection of one or more minerals or other rock and mineral debris during geological processes. The rocks in nature are diverse, and the rocks are divided into three categories, namely magmatic rocks, sedimentary rocks and metamorphic rocks. Magmatic rock is a rock formed by underground magma intrusion into the earth's crust or sprayed cold and solidified on the surface, also known as igneous rock; sedimentary rock is composed of surface rock weathering (sand, rock debris, mineral debris, chemically dissolved matter, etc.) The rock formed by sedimentation, sedimentation, and long-term sedimentary diagenesis, also known as sedimentary rock; metamorphic rock is the condition that the original rock is basically kept solid due to temperature, pressure, and hydrothermal participation. Rocks formed by changes in structure, structure, or composition of matter. The three types of rocks can be transformed into each other. The magmatic rocks and metamorphic rocks are continuously weathered, denuded, transported and deposited to form sedimentary rocks under the surface and external geological forces; magmatic rocks and sedimentary rocks are transformed into metamorphic rocks under metamorphism; buried in the earth's crust The sedimentary rocks and metamorphic rocks in the deep remelted under high temperature and are transformed into magma. After the magma is condensed, magmatic rocks can be formed. Green curtain granite, magma rock, used as a decoration Sedimentary rock The proportion and distribution of the three major rocks in the earth's crust are relatively complicated. According to statistics, in the volume of the crust, as far as 16km, more than 95% are magmatic rocks and metamorphic rocks, and sedimentary rocks only account for 5%. However, the sedimentary rocks on the surface are widely distributed, and about 75% of the surface is covered by sedimentary rocks. Magma rocks are the most abundant in the earth's crust, accounting for about 80% of the total mass of the earth's crust. The entire oceanic crust is composed entirely of magmatic rocks. Metamorphic rocks are also widely distributed throughout the world. Their distribution is characterized by the fact that most of the Precambrian strata are composed of metamorphic rocks. After the Paleozoic, the crustal activity belts in various geological periods, some intrusive zones and fault zones There are distributions of metamorphic rocks. The beautiful stone is jade, and it can be regarded as jade whether it is magmatic rock, sedimentary rock or metamorphic rock. However, in particular, common jade varieties are characterized by metamorphic rocks, such as jade, Hetian jade, jade, quartzite (Huanglongyu, Taishan jade, Dongling stone, etc.), Shoushan stone, bloodstone, Guanglu jade, marble, and so on.
