浊流沉积和等深线沉积被称之为近代沉积岩石学中的两次革命。一九八二年及一九八三年,笔者先后在珲春县马滴达乡南山二叠系及怀德县黄岭子乡奥陶系石缝组两处古生代地层中发现和确定了浊流沉积。为引起有关地质同行的关注,简单报导如下:珲春县马滴达乡南山二叠系的浊流沉积十分典型。从剖面的底部,由高密度浊流所形成的含砾粗——细砂岩构成块状的粒序(递变)层;一直到剖面顶部,由低密度浊流所形成的泥质岩石,呈现
Turbidity flow and isobaric deposition are called two revolutions in modern sedimentary petrology. In 1982 and 1983, the author discovered and determined turbidite sediments in two Paleozoic strata of the Ordovician Seishan Formation in Maitadag Township, Huichun County and successively in the Nanshan Permian in Maitadag Township, Huichuang County. In order to arouse the concern of geologic counterparts, the brief report is as follows: The turbidity current deposition of Nanshan Permian in Maitida Village, Qichun County is very typical. From the bottom of the profile, gravelly coarse-fine sandstone formed by high-density turbidity constitutes a massive graded (graded) layer; shaly rock formed by low-density turbidity currents up to the top of the profile presents
