| 摘 要： | 以野外地质调查资料及岩石薄片为基础,通过研究贺兰山苏峪口正目观组冰碛砾岩的各种形态特征,依据冰川沉积学、沉积岩石学及古地理学等对苏峪口冰碛砾岩的形成环境进行分析.研究得出:该套冰碛砾岩是冰川搬运大小不等的岩块至苏峪口进行堆积,接着是海侵阶段,致使冰块周围水体温度升高,携带于冰块内的岩块、岩屑由于冰块的消融坠沉到海底还未固结的砂泥纹层上,并逐渐为碳酸盐泥晶掩埋形成. |

| Abstract: | This paper analyzed the genetic environment of tillite in Zhengmuguan formation based on the data of geological survey in field and petrographic thin slices through the study of various characteristics of tillite in Zhengmuguan formation,Suyukou,Helan mountain and according to the knowledges of glacial deposit,sedimentary petrography and paleogeography.The genetic analysis results were that this set of tillite was formed by the glaciation in which different sizes of rocks were carried into Suyukou and depos... |
