叠锥构造是沉積岩中極有兴趣的构造之一,在柴达木盆地的东北缘,曾先后在魚卡及赛冷朶秀(旺朶秀)發現过叠锥構造。賽冷朶秀所見叠錐構造系產于石炭紀地层中,当地石炭纪系海陸交互相的含煤系,主要岩性为石灰岩及砂、頁岩,並含煤层:叠锥构造即產于石炭纪地层的中下部,主要岩性为石灰岩及頁岩,在頁岩中也常夾有石灰岩的凸鏡体,凸鏡体大小不一,可由几公尺到几十公尺,/而叠錐構造即產于石灰岩凸鏡体中,叠锥大小不一,但發育尚佳。
Stack cone structure is one of the most interested structures in sedimentary rocks. In the northeastern margin of the Qaidam Basin, it has discovered the overlying cone structure in fish cards and Sai Leng Du Sau (Wang Duo Sau). The structure of the cone cone seen in Sai Leng Duo Xiu is a coal-bearing series of marine-continental interaction facies in the Carboniferous strata in the Carboniferous strata. The main lithology is limestone and sand, shale and coal-bearing strata. The cone-fold structure is produced in the Carboniferous The middle and lower strata, the main lithology of limestone and shale, shale often sandwiched limestone convex mirror body, convex mirror body of different sizes, from a few meters to tens of meters, and the cone structure that is produced In the limestone convex mirror body, cone stack size, but development is still good.
