摘　　要：秦巴山区按地质成矿特征可划分大巴山、平利、南秦岭三个区。重晶石与毒重石矿床分三条成矿带 :南带为毒重石矿带、北带与中带为重晶石矿带 ,成矿具有多期作用 ,含火山喷发、大陆边缘沉积、裂谷与脉体成矿叠加。本区找矿前景是乐观的。The Qinling mountainous area may be distinguished, depending to geological features, into three different parts, Dabashan, Pingli and South Qinling respectively corresponding to northern, middle and southern metallogenic belts. The northern and middle belts host barite deposits while the southern belt contains witherite deposits. Mineralizing events were caused by epicontinental deposition and rift volcanic eruption, showing a rift controlled, vein injecting, multiperiodic mineralization.
