Sandstone material classification
Sandstone can be roughly divided into three categories according to different formation modes: igneous rock, sedimentary rock and metamorphic rock.
Igneous volcanic rock rhyolite; coarse shale; Xiangyan; Ying'an rock; andesite; rough rock; basalt
Shallow porphyry; fine rock; fine-grained rock; pegmatite; porphyrite; granitic rock; lamprophyre
Sedimentary granite; syenite; monzonite; granodiorite; diorite; gabbro; plagioclase; peridotite; pyroxenite; hornblende rock; serpentinite; serpentine marble; Carbonate rock
Sedimentary rock clastic rock; conglomerate; breccia; sandstone (also divided into feldspar sandstone, miscellaneous sandstone); mudstone; shale; slate
Volcanic clastic rock agglomerate; tuff
Biological rock limestone; vermiculite; diatomaceous earth; stratified rock; coal; oil shale
Chemical rock limestone; dolomite; vermiculite
Metamorphic rock contact metamorphic rock shale; marble; quartzite; skarn; Yunyingyan
Regional metamorphic rock phyllite; schist; gneiss; mixed rock; amphibolite; granulite; eclogite
Dynamic metamorphic rock mylonite
Carbon and its compounds A wide variety of carbons can also be alloyed with iron, the most common being carbon steel; graphite and clay can be used to make pencil cores for writing and painting, and graphite can also be used as a lubricant and pigment as a glass. Molding materials for electrodes and electroplating, electroforming, electric motor brushes, and neutron deceleration materials in nuclear reactors; coke can be used in barbecue, drawing materials and ironmaking industries; gem-quality diamonds can be used as jewelry, industrial Diamond is used for drilling, cutting and polishing, as well as tools for machining stones and metals.
