| 摘 要： | 本区地壳演化分：太古—早元古代构造基底形成、中晚元古代大陆边缘、早古生代裂谷形成与晚古生代海槽演化四个阶段。重晶石矿床成矿作用有火山喷流作用、大陆边缘沉积作用与裂谷带多种成矿作用的叠加，是形成大型超大型重晶石矿床重要特征。本区寻找重晶石矿前景是乐观的。

| Abstract: | The crustal evolution in this area is divided into four stages: (1) structural basement formation in Archean era-Proterozoic era, (2) middle-late Proterozoic continental margin,(3) early Paleozoic rift formation, and (4) late Paleozoic trough evolution. The principal characteristics of mega-ultramega barite deposite formed are that many ore-forming process which include volcanic eruption, continental marginal sedmentation and rift zone over-printed on barite deposit mineralization. The prospect of barite deposit exploration may be exciting in this area. |
