摘要 滇西耿马盆地位于三江褶皱系保山褶皱带的耿马—澜沧复背斜,面积195km2,接受广泛的河湖相沉积,为典型的第三系小型陆相盆地。盆地内沉积受构造控制明显,沿边界断层主要发育冲积扇、近岸水下扇沉积,远离断层发育深湖相或半深湖相沉积。耿马盆地的构造样式与沉积展布在滇西具有极好的代表性,故从构造-沉积相互作用角度对其分析,对于指导滇西其他第三系盆地的勘探有重要意义。 The Gengma basin located in the Gengma Liangchuang anticlinorium of Baoshan fold belt,Western Yunnan is 195 km 2 in area, accepted widespread fluviol acustrine deposit, and is typical Tertiary small continental basin. The deposit in the basin is controlled by structure evidently, along the boundary fault, the alluvial fans and inshore submarine fans developed, and far away from the boundary fault, the deep lacustrine facies and hypabyssal lacustring facies developed. The tectonic styles and sedimentary spreads is very typical in Western Yunnan, so to analyze the basin from the interaction between the tectonic and sedimentation has important directive meaning for the exploration of other Tertiary basins in Western Yunnan.
