The origin of garnet

Magnesia aluminite is mainly produced in ultrabasic rock and residual slope placer, and large gemstone grade magnesia aluminite is rare. The former Soviet Union, Norway, Czech Republic and Jiangsu of China have output; Ferromagnesia garnet is mainly produced in the United States and Tanzania and other countries; Ferro alu garnet is produced in mica schist, hornblende gneiss and other metamorphic rocks and placers, and is produced in Sri Lanka, Brazil, Madagascar, India and other countries. Calcium-aluminite is a product of skarn, but it is also found in serphoserite and gabbro alteration zones, such as Kenya, Pakistan, the former Soviet Union and China produced green calcium-aluminite garnet. Cassia garnet from Sri Lanka; Manganal garnet is produced in pegmatite and some metamorphic rocks. Gem-grade manganal garnet is produced in Myanmar, Sri Lanka, Brazil and other countries. Calcium and iron garnet is the product of schist and metamorphic limestone belt, brown and green, green garnet and green garnet are produced in serserite, black garnet is produced in alkaline igneous rock, in the former Soviet Union and Congo. Calcium-chromic garnet is the product of the interaction of gas-generated hot water solution with calcium-containing ultrabasic rocks, which was found in the former Soviet Union and the United States.
