| Abstract: | This paper discribes the size, petrological-mineralogical, surfaee and part of physical characteristics of till in Tianshan Mountain in China and the Soviet Union on the basis of contracting the analytical results of the till-soil samples taken from Tuyuksu Glacier in the Soviet Union, with the rekereme of the doccuments about the till in Tianshan Mountain by both Chinese and Russian scientists.The characteristics include: (1) wide distribution and various types; (2) breccia-soil fillers (<32 mm) which are mainly composed of graval and sand with inferior size grading; (3) complex clastic composition (over 40 species); (4) debris inferiorly abraded; (5) low maturity of light minerals; (6) distinct striae on the surface of bouldev and quartz sand; with conchoidal fracture; (7) high natural unit weight and generally low natural water content. |
