加拿大萨斯克彻温盆地钾盐矿矿床地质特征及勘查路径

Deposit Geological Characteristics and Prospecting Paths of the Potassium Salt Mine in the Saskatchewan Basin in Canada

加拿大萨斯克彻温盆地是世界上最大的固体钾盐成矿带,该盆地钾盐矿矿体虽较为稳定、连续,但几乎所有的勘查区都或多或少仍存在"凹陷"、"隆起"等破坏性构造,这对前期勘查投入及后期开发都将产生较大的风险。总结该钾盐盆地矿床地质特征,并提出物探先行、钻孔验证,逐步加密、循序渐进的综合勘查路径。

The Saskatchewan Basin in Canada is the world 5s largest solid potassium mineralization belt. Although the ore body of potash in this basin is relatively stable and continuous, almost all the exploration areas still have some destructive structures, such as ＂sag＂ and ＂uprise＂, which will have great risk to the early exploration investment and later development. This paper summarizes the geological characteristics of the deposit in the potassium salt basin, and puts forward the comprehensive exploration path of geophysical prospecting, drilling verification, gradual encryption and gradual progress.
