青藏高原东缘山地古冰川沉积物化学参数指示意义

Ancient glacial sedimentchemical parametersindicating significancein the eastern margin mountains of the Qinghai Tibet Plateau

对于冰川沉积物化学特征的分析,可以有效地反映当地古环境的气候状况,本文通过对青藏高原东缘的古冰川山地的冰碛物进行采样,结合部分其他山地样品数据,进行地球化学元素实验,计算以及对比其化学参数。得到青藏高原东缘等十处古冰川山地冰川沉积物化学组分构成,利用CIA等参数分析其对当地环境的指示意义。

Analyzing the glacial sediment chemical features, which can reflect the climate condition of the local environment effectively. We take a sample ofancient glacial mountains sediment,combine some parts of other mountains samples, experimenting onthe geochemical element. Then we compared them and calculate their chemical parameters. Concluding the ancient glacial sediment compose in the eastern margin mountains of the Qinghai Tibet, and its significance of local environment.
