Characteristics of subsurface brine salt deposits

Subsurface brine salt deposits refer to salt deposits occurring in a liquid-phase state in subsurface strata. They can be formed in both ancient and modern times. The subsurface brine salt deposits formed in modern times have been discussed in the previous paragraphs pertaining to liquid-phase saline-lake salt deposits.

The ancient subsurface brine salt deposits will be dealt with in the following text.The anicent subsurface brine salt deposits of China are mainly distributed in Sichuan, Hubei and other provinces in the central part of China and are most concentrated in the Zigong area of Sichuan Province.

The subsurface brine salt deposits can be divided into 3 genetic types:

1) Sedimentary type brine deposits.

The subsurface brine with a high total solinity, also termed the primary connate brine, was formed as a result of the concentration and metamorphism of the fossil seawater that had been stored between sand grains in the diagenetic process or had entered pores and fissures after the diagenesis of sedimentary rocks.Henan Hongxing Mining Machinery Co., Ltd is the professional manufacturer of complete sets of mining machinery, for example,flotation cells,sand washing machine Welcome all of you to visit our official website.rock crushers:http://www.crusher-machine.com/1.html

2) Leaching type brine deposits.

The subsurface brine was formed as a result of accumulation of the ground water that had dissolved the saline materials in rock beds or mineral deposits in the process of its movement.

3) Mixed sedimentary-leaching type brine deposits.

The subsurface brine was formed by the mixing of the sedimentary type brine with the leaching type brine in the process of their underground migration.

Subsurface brine salt deposits are divisive into 3 groups as follows:

1) Porous type subsurface brine deposits.

They are represented by the Qianjiang subsurface brine salt deposit in Hubei Province.

2) Fissure type subsurface brine deposits.

The representative deposit is the Zizhong subsurface brine salt deposit in Sichuan.

3) Combined pore-fissure type subsurface brine deposits.

The Baimuqiao mirabilite-brine deposit in Danling County, Sichuan is their representative.
