| 摘 要： | 以安棚天然碱矿为例,通过分析泌阳凹陷天然碱矿的地质特征、底面构造特征、矿石特征,论述天然碱矿成矿地质条件、矿床成因,对天然碱矿进行了成矿预测。指出凹陷内安店次凹和程店次凹可能会有天然碱矿;南阳凹陷的汉冢、桐寨铺次级凹陷可能会存在碱矿,碱卤水层物质来源具有深源性;提出了钾、锂等矿床的勘查方向。

| Abstract: | Taking Anpeng trona deposit as an example, analyzed geological characteristics of natural soda deposit in Biyang depression are analyzed, the structural characteristics of bottom surface, ore metallogenic conditions and genesis are discussed. And the ore prediction is made. It is pointed out that in Andian sub-depression and Chengdian sub-depression in Biyang depression may occur trona ore and in Hanzhong sub-depression and Tongzai sub-depression could occur trona ore in Nanyang depression and the alkaline brine is of deep source. Then prospecting direction of potassium and lithium is put forward. |
