四川盆地地下卤水资源优势及综合开发前景

四川盆地地下卤水自震旦系至白垩系各层系皆有分布。卤水具有分布广泛、资源丰富、品质优异、高承压及气卤同产等优势特点,是四川得天独厚的液态矿产资源。卤水中含有K+、Br-I、-、B3+、Li+、Sr2+、Rb+等多种有用组分,皆为国家紧缺和紧俏物质,其含量多数可达工业开采品位,为优质化工原料水,经济价值极高,综合开发利用前景广阔。

Resource Advantages of the Underground Brines of Sichuan Basin and the Outlook of Their Comprehensive Exploitation

Underground brines in Sichuan Basin are found in each stratum from Sinian to Cretaceous.The brines feature the characteristics of broad distribution,resource abundance,high quality,high pressure,and coexistence with gases,which make them as wonderful natural liquid mineral reserves for exploitation.The brines contain many useful components such as potassium,bromine,iodine,boron, lithium,strontium,and rubidium,which are very needy in the domestic market.Their contents generally meet the grades for mining.Therefore,the comprehensive utilization of the brine resources is of great economic significance.It is believed that the outlook for their exploitation is very promising.
