| 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. |
