刚果布谷马西矿区北部矿段钾石盐矿床地质特征

Geological Characteristics of Potash Deposit in Northern Section of Bugumaxi Mine in the Republic of Congo

摘要:

布谷马西矿区北部矿段钾盐矿为大型矿床，共圈出钾盐矿层16层，其中钾石盐型矿层3层，赋存于光卤石岩上部。钾石盐型矿层赋矿标高260.83～321.32m，估算KCl（333）资源量1743.5万t，KCl平均品位23.02%。矿床成因类型为后生淋滤成因。

Abstract:

Potash deposit in northern section of Bugumaxi mine is a large deposit, and 16 layers potash ores have been circled. Among them, 3 are potash type layers and occur in the upper part of carnallitolite. The level of deposit occurrence is 260.83 ~ 321.32m, estimated amount of KCl (333) is 1743.5 ten thousand tons, and the average grade of KCl is 23.02%. The genetic type of deposit is epigenetic leaching type.
