在德国Alfred-Wegener极地与海洋研究所用自动组构分析仪G50测试了东天山庙儿沟冰芯(43°03’19″N,94°19’21″E,4 512 m a.s.l.;2005年钻取,长58.7 m)冰微构造和组构,分析其特征并解释其所蕴含的意义。冰微构造和组构随深度的演变总体相似于其他中国山地冰川冰的观测结果,同时展示了其季节性特征。部分样品的测试结果有所波动,可能是样品在运输和存储过程中的热力学性质发生改变所致。组构型反应的力场较为简单,主要为中下部的单轴压应力作用。正常晶粒生长、多边形化作用和应变导致的边界迁移再结晶不能解释其在某一深段占据主导,而可能是三者共同作用于所有冰芯深部。
In Germany, the Alfred-Wegener Institute of Polar and Marine Mechanisms used an automatic fabric analyzer G50 to test the Miaogou ice core (43 ° 03’19 “N, 94 ° 19’21” E, 4 512 m asl; Take, long 58.7 m) ice micro-structure and fabric, analyze its characteristics and explain its implications. The evolution of ice microarchitecture and structure with depth is generally similar to the observations of glacier ice in other mountainous areas of China, and shows its seasonal features. The test results of some samples fluctuate, which may be caused by the change of the thermodynamic properties of samples during transportation and storage. The force field of the structure reaction is relatively simple, mainly for the uniaxial compressive stress in the middle and lower part. Normal grain growth, polygonization and strain-induced boundary migration recrystallization can not explain its domination in a certain depth, but probably the three act together on all ice core deep.
