| 摘 要： | 位于西藏东部的三江地区北部累计厚度达１００００余米的三叠系以海相沉积为主，由碎屑岩、碳酸盐岩和火山岩的一种或两种占优势的组分构成。其以陆源、内源及火山源碎屑流与浊流形成的深水沉积为特色，并分别堆积在不同背景的江达弧内盆地和生达弧后区的沉积盆地中，研究表明这些深水沉积应是活跃的构造作用的响应，对认识三江地区的构造活动具有指示意义。

| Abstract: | Triassic strata with more than 10000 m in thickness are dominated by marine sediments in northern Three-River area of eastern Tibet. Composed of one or two dominant components of clastic, carbonatic and volcanic rocks, the sediments are characterized by abyssal sediments formed by debris flows and turbidities of terrigenous, basinal and volcanic sources, and accumulated in Jomda arc basin and Sinda back_arc basin. The deep-water sediments seem to be the response to active tectonics, and hence are of indicating significance to trace tectonic activity in
Three-River area. |
