| 摘 要： | 罗北凹地液体钾矿床位于新疆罗布泊地区北部,是一个大型的综合性盐类矿床。对矿区两处"成矿远景区"进行专门研究,从其与相邻地带的地层接触关系、水文地质和氢氧同位素条件分析,指出此区具备与罗北凹地相似的液体钾矿成矿条件,仅地层时代不同期,与矿体边界及周边湖岸阶地形成一种地垒模式,为指导在本地区或其它类似地区寻找新的不同时期、相同成矿条件的成矿带提出一种成矿模式。

| Abstract: | Liquid potash deposition of Luobei depression is located in the north part of Lop nur region in Xinjiang and belongs to the large comprehensive salt deposition. The authors specially researched two places of the prospective area, it was found that they had similar metallogenie condition compared with Luobei depression including strata contact relations, hydrogeology and hydrogen oxygen isotopes, but different periods. They formed a horst with lakeshore terrace and ore body boundary. The ＂ isogenous, honsynchronous＂ metallogenic model can be proposed to guide metallogenic belt finding. |
