| 摘 要： | 建立在对断裂带的变形特征、运动学特征和变形岩石年代学的综合研究表明，澜沧江断裂带是一条左旋走滑断裂带，左旋走滑始于20Ma。印支地块由南北向北运动和保山地块的向南挤出，主要是通过红河断裂、怒江断裂的右旋走滑和澜沧江断裂的左旋走滑共同调节来实现的。澜沧江断裂带的左旋走滑制约了临沧帮卖盆地的形成演化、盆地内的热水活动、锗的富集成矿和锗矿床的空间分布。

| Abstract: | Comprehensive studies, based on the characteristics of deformation, movement and chronology of deformation rocks in the fault zone, suggest that the Lancang River Fault Zone (LRFZ) with left slip has begun its strike slip since 20 Ma. The northward Indochina Block translation and Baoshan Block translation southwards were modulated by right slip of the Red River fault and the Nu River fault, and let slip of the LRFZ. The left slip of the LRFZ was responsible for the development and evolution of the Bangmai basin, activity of thermal fluids, Ge enrichment mineralization and Ge distribuation in the basin. |
