The Hydrochemistry and Isotope Geochemistry of Brines Which Enrich in Potash,Boron and Bromine in Pinlopa Well 4 in Chengdu Sold Basin
中国东南陆缘区中生代膨润土矿床同位素地球化学研究

From the date of evolutional history of the solt basin,chemical composition; hydrogen,oxygen,sulfur and boron isotopes compositions,it can be concluded that this brine is related to mixecl type,of marine_continental phases. Envichment in same elements is resulted by mixing of introduced brines and formation water and dissolution of solt basin at evaporation conditions during the late period of brine_solt forming procees.
