四川盆地卤水钾资源分布类型及其品质的研究

四川盆地三叠纪海相沉积层屡有地下卤水,品质优异,除普遍含K+,构成液态钾资源外,并伴生Br-、I-、B3+,Li+等多种有用组分,经济价值极高。卤水钾有沉积变质型和与钾盐溶滤叠加型两类。对局部构造深层卤水储量,在当前条件下,可采用容积法计算。对其开发利用可为我国钾盐提供新的矿物原料。目前需要对卤水钾资源的资产意识问题、开发利用及环境问题、地质勘查及相应的研究问题、开发的统一部署问题,认真加以解决。

DISTRIBUTION TYPES OF CHARACTERS OF POTASSIUM- BEARING BRINE RESOURCES IN SICHUAN BASIN

The Triassic marine sedimentary strata in Sichuan basin tend to embody high-quality underground brine that enjoys a very great economic value due not only to commonly containing enough potassium to constitute a certain quantity of potassium resources but to being associated with Br-, I-, B3+, Li+, etc., useful components.The potassium resources can be classified into two types, metamorphic and repeatedly leaching. Reserves of deep potassium-bearing brine resources may be calculated today by using a volume method and developed so as to provide our potash industry with a new alternative raw mineral. At present, it is necessary to give serious consideration to such some problems as how to be aware of potassium-bearing brine as a resource, how to develop them and protect environment, how to geologically prospect for them, and how to carry out the prospecting works with a the principle of overall consideration.
