| 摘 要： | 双溪堆积体是大宁河上游广泛发育的、钙质胶结的碎石土堆积体，其成因与大宁河流域新近系不同时期发育的崩塌、滑坡和泥石流有密切的关系。在大宁河沿岸的双溪、中坝、神基坪一带，志留系泥岩粉砂岩等易风化软弱碎屑岩构成斜坡下部相对较缓的部位，二叠系或三叠系相对坚硬的灰岩则形成斜坡上部高陡的崖坡，坡脚则广泛分布着这种钙质胶结的双溪堆积体。

| Abstract: | The Shuangxi deposition is made of detritus and distributed abroad along the upper reach of the Dalinghe river.It has close relations with rockfalls,landslide and debris flows.At Shuangxi village,Zhongba village and Shenjiping village along Daninghe river,the mudstone and siltstone rocks of the Silurian age are soft and can be easily weathered.They are distributed at the lower and gentle slopes.The limestone of the Permian and Triassic age are distributed at the upper and steep slopes.It is hard and solid.T... |
