摘要

色楞嘎河右岸的阶地高60-65米，由粗粒和非圆状和略圆状的粗粒物质混合组成。沉积物分选以次水平和倾斜分层为主。沉积岩具有相同的构造和结构特征，但成因不同:乌斯特—济达盆地以湖相冲积为主，河流和斜坡物质混合;Gusinoozerskaya盆地以湖相冲积为主，形成非河道和洪泛平原相。

Genesis of Sediments from high Terraces in Selenga River, the Ust’-Dzhida and Gusinoozerskaya Basins of Western Transbaikal

On the right bank of Selenga River, terraces as high as 60–65 m are composed of aleuritic-sandy sorted sediments with a small admixture of non-rounded and slightly-rounded coarse material. The sediments are sorted with subhorizontal and inclined stratification. Sedimentary rocks with common structural and textural characteristics show different genesis: in the Ust’-Dzhida basin mainly lacustrine-alluvial, with an admixture of river and slope material, in the Gusinoozerskaya basin – alluvial with the formation of non-channeled and floodplain facies.
