表文以“七1”冰川流域冰碛石和冰水砾石的组构测量为依据,对沉积物的组构特征及其与沉积环境的关系作了比较全面地讨论,冰碛石粒度频率曲线呈多峰式,粒度分选作用极差,σ_1>2,SK_1>0或<0,Kg<0.72,大多数冰碛石的长轴平行于冰流方向,冰水砾石呈双峰式,分选作用中等,δ_1=1.4-2, SK_1>0, Kg=0.92-1.14,大多数a轴平行于河流流向;C轴指向下游;ab面逆流倾斜,平均倾角30°左右,作者指出,冰碛石和冰水砾石的组构特征,对于研究沉积环境和鉴定古冰川、冰水沉积的成因类型有着重要的意义。
Based on the tectonic measurements of the moraine and ice-water gravels in the “Glacier Basin”, the relationship between the structural features of the sediments and the sedimentary environment is discussed in more comprehensive terms. The granulometric frequency curve of the moraine was Multi-peaked, fine-grained separation with extremely poor function, σ_1> 2, SK_1> 0 or <0, Kg <0.72. Most of the moraine rocks have long axes parallel to the direction of ice flow. Moderate δ_1 = 1.4-2, SK_1> 0, Kg = 0.92-1.14, most of the a-axis parallel to the river flow direction; C-axis downstream; ab reverse flow slope with an average inclination of about 30 °. The structural features of ice-water gravel are of great significance for the study of sedimentary environment and the identification of genetic types of pale-glacial and ice-water sediments.
