Study on the Relationship between the Depositional Environment and Minerallization of Fugu Kaolinite Deposit in Shanxi Province

Analysis of the kaolinite deposit and its ore-deposition environment shows that the areas of Fugu hard sedimentary kaolinite deposits were formed respectively in the lake controlled by freshwater behind the coast, the lake between distributary channels, delta plain lakes and medering riparian lakes. Deposits formed in different sedimentary environments varies in orebody characteristics, ore types and industrial uses. The Deposits formed in the lake controlled by freshwater behind the coast and lake between distributary channels have a large scale and a wide distribution, however, because of the low kaolinite content, high impurity content, and poor quality of the kaolinite, their industrial uses were limited in Porcelain Manufacture. In contrast, the deposits formed in delta plain lakes and meandering riparian lakes are relatively smaller, whereas due to high kaolinite content, low impurity content, and good quality, this kind of kaolinite has many advanced industrial applications, such as paper coating and molecular sieve. The research is helpful to the exploration and industrial utilization of kaolinite deposit.
