Classification of Rocks-Yicang Science and Technology Drill Pipe Spiral Drill Pipe Diamond Bit Factory Outlet Rocks can be divided into three categories: 1. Magmatic rocks (spouted rocks) 2. Sedimentary rocks 3. Metamorphic rocks 1. Magmatic rocks mainly include granite, andesite, diorite, rhyolite, basalt, gabbro, etc. 2. Sedimentary rocks mainly include: quartz sandstone, lime conglomerate, mudstone, dolomite, mudstone, gypsum, etc. 3. Metamorphic rocks mainly include: gneiss, chlorite schist, phyllite, marble, mica schist, etc. Although the appearance of rocks is ever-changing, but from their formation environment, that is, from the cause of division, can be divided into rocks

Rock can be divided into three categories: 1, magmatic rock (rock)2Sedimentary rock3Metamorphic rock
1、 Magmatic rocks mainly include granite, andesite, diorite, rhyolite, basalt, gabbro, etc.
2,Sedimentary rocks mainly include quartz sandstone, lime conglomerate, mudstone, dolomite, mudstone, gypsum, etc.
3,Metamorphic rocks mainly include: gneiss, chlorite schist, phyllite, marble, mica schist, etc.
Although the appearance of rocks is ever-changing, but from their formation environment, that is, from the cause of division, rocks can be divided into three categories: sedimentary rocks, magmatic rocks and metamorphic rocks
1、 Sedimentary rock: Sedimentary rock is a rock type formed on the surface or near the surface of the earth. It is a rock formed by weathering products, volcanic materials, organic materials and other clastic materials after transportation, deposition and petrochemical under normal temperature and pressure. Either way, the clastic material is transported, then deposited in a suitable environment, and after a long process of compaction, petrified into hard sedimentary rocks. Sedimentary rocks are divided into conglomerate, sandstone, shale and limestone according to the size of sediment particles. Formation of sedimentary rocks: 1. Weathering and erosion: large rocks on rivers have been eroded over the years and gradually disintegrated into small silt and debris.2Handling: The debris is carried by the water flow from upstream to downstream.3Accumulation: The downstream flow velocity slows down, the carrying force decreases, and the rock debris is deposited.4, compaction: the new sediment is pressed on the old sediment, and over time, the sediment at the bottom is compacted more tightly.52. Cementation: Groundwater passes through the pores of the sediment, and the minerals brought by it fill the pores, so that the rock debris particles are tightly cemented together to form sedimentary rocks.6Exposed: Sedimentary rock layers deposited on the seabed arch out of the sea surface under the push of plate movement, exposing the surface.
2,Magmatic rocks: Magmatic rocks, also known as igneous rocks, are magma formed in the depths of the earth's crust or in the upper mantle, intruding into the upper part of the earth's crust or ejected from the surface to cool and solidify and form rocks through crystallization. Because the conditions of its formation and sedimentary rocks are very different, its characteristics are obviously different from sedimentary rocks. Magmatic rocks are divided into andesite, basalt and granite. There is underground magma cooling solidification formation. Different igneous rocks are formed due to different magma compositions and cooling methods. The formation of magmatic rocks: 1, andesite: magma from the crater out of the ground, rapid cooling formation.2Basalt: Magma flows out through a moderate eruption and gradually condenses.3Granite: Magma is not ejected from the ground, but slowly cooled underground.
3,Metamorphic rocks: During the formation and development of the earth's crust, the rocks formed earlier, including sedimentary rocks and magmatic rocks, have undergone mineral composition adjustments, structural changes and even chemical changes in the solid state due to changes in the geological environment and physical and chemical conditions. The change of composition forms a new kind of rock, which is called metamorphic rock. Metamorphic rocks are one of the most important rock types in the continental crust. Metamorphic rocks are divided into slate, schist, gneiss and marble. Formation of metamorphic rocks: 1. Rock strata before metamorphism: due to sedimentation or volcanism, layers of rock strata are accumulated.2Extruded rock formation: under the action of strong pressure and friction, temperature and pressure are generated, which makes the deep underground rock metamorphism occur.3Metamorphism into new rocks: the scattered mineral crystals in the rocks will be arranged regularly, or new minerals will be generated and turned into various new metamorphic rocks.
