泥岩、粉砂岩属于稳水环境下形成的沉积岩 ,其沉积环境一般为滨海或河、湖。根据尤尔斯特隆沉积规律 ,一般水流速在 1cm/s时粉粒即可沉积 ,经漫长的地质历史时期形成沉积岩。穆棱河青龙山水库坝址区分布较多泥岩及粉砂岩 ,由于其工程地质特性 ,对水工建筑物的布置产生了一定影响。 Mudstone and siltstone are sedimentary rocks formed under steady water environment. The sedimentary environment is generally coastal or river and lake. According to Julestrong deposition law, the general water velocity at 1cm / s when the particles can be deposited, formed by the long geological history of sedimentary rocks. Muling River Qinglongshan reservoir dam site distribution more mudstone and siltstone, due to its engineering geological characteristics, the layout of hydraulic structures have a certain impact.
