| 摘 要： | 勉县－略阳与大巴山区分火山岩与沉积岩两大成矿区，可划分４种主要的重晶石类型含磷（铀）型重晶石（东风沟式）、多金属矿型重晶石（东沟坝式）、沉积型重晶石（水平式）和沉积型伴生重晶石的毒重石（冉家坝式）矿床。重晶石成矿条件（钡源、构造条件与沉积环境）及成因机理各不相同。

| Abstract: | Four major types of barite deposit have been mapped from the meeting area of Shaanxi, Gansu and Sichuan provinces including volcanic rock rich Mianxian Nueyang subarea and sedimentary rock rich Dabashan mountain subarea. They are phosphorus (uranium) carrying Dongfenggou type, polymetallic Donggouba type, sedimentary Shuiping type and witherite accompanied Yuanjiaba type, each having mineralizing condition and mechanism of its own. |
