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。
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 metallo- genic 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.
