本文通过对疏勒南山岗纳楼冰碛物的沉积组构分析,提出了现代冰碛物的主要组构特征。水碛物成分组合简单,粒度分选作用极差。分选系数在5.14以上,平均园度约为20%。大多数冰碛石的长轴平行于其沉积时期冰川流动的方向。a轴指向N75°-89°W——S75°-89°E倾角0°-25°。沉积组构分析的方法是说明冰川沉积作用、冰成沉积物形成机理的一种有用的工具。此外,现代冰碛物的组构特征,对于研究古冰碛和冰碛岩也有着重要的意义。
In this paper, the main structural features of modern moraines are proposed by analyzing the sedimentary structure of the glacial moraines at Gulou Nanshan Gulou. The composition of the moraine composition is simple, the particle size separation is very poor. The sorting coefficient is above 5.14, and the average garden degree is about 20%. The major axis of most moraine rocks is parallel to the direction of glacier flow during its deposition. a-axis pointing at N75 ° -89 ° W-S75 ° -89 ° E tilt 0 ° -25 °. The method of sedimentary structure analysis is a useful tool to illustrate glacial sedimentation and ice formation. In addition, the structural features of modern moraines are also of great significance for the study of ancient moraines and moraine rocks.
