| 中文摘要: |
| 金顶锶矿位于高坪—老母井向斜东翼、沘江大断层西侧,为一穹隆构造。沘江大断层为主要导矿构造,穹隆体和F2断层破碎带为重要容矿构造。F2断层下盘云龙组地层中的有利岩性是锶矿体的主要赋矿部位。根据金顶矿区地质特征分析,在有机质和生物的参与下,富含金属组分的高盐度热卤水沿导矿构造循环至有利的岩层和构造部位逐步沉淀富集,最终形成金顶锶矿床。笔者认为金顶锶矿矿床成因是以热卤水为主的多成因的层控锶矿床。 |
| 英文摘要: |
| The Jinding strontium deposit is located in the eastern side of the Gaoping - Laomujing syncline, and the western part of the Bijiang fault which forms a dome structure. The Bijiang fault is the main fluid-passing structure, while the dome and F2 fault zone are the main ore-bearing structures. The favorable lithology in the Panyunlong formation in the footwall of the F2 fault is the main host rock of the strontium orebody. Based on the analysis on the geological characteristics of Jinding deposit area, the deposit was formed by the high salinity hot brine under the participation of the organic matter and biological matter. The hot brine fluid rich in metal component flew to the favorable rock and the tectonic position along the fluid-passing structure, gradually precipitated and accumulated and finally formed the Jinding strontium deposit. The authors thinks that Jinding strontium deposit is a multiple genesis strata-bound strontium deposit which is mainly dominated by the deposition of hot brine. |
