成都平原西部汞异常探秘

富饶美丽的成都平原，而今却承受着污染的困扰。早在７０ 年代，有关部门就已发现汞污染十分严重。通过一系列探索性研究之后，仍然对汞污染的来源不甚明了而成为谜团。本文通过对地质背景来源，汞的地球化学特征，新一轮地化测量工作的启示，并结合成都平原的基底断裂特征进行探索，初步认为成都平原的汞污染除人为来源之外，还可能与成都平原下，沿基底断裂所产生的地球脱气作用有关。

EXPLORATION OF MERCURY POLLUTION OF CHENGDU PLAIN

The wide Chengdu plain is very beautiful and fertile. But nowadays, it is puzzled by many kinds of pollutions. Even early in 1970's, some government departments noticed the serious mercury pollution in this plain. Though a series of researches were done, the pollution sources could not be found out. It seems as if a puzzle. In this paper both the geologic background of some the pollution sources in the Chengdu plain and the features of geochemistry have evidentl been correlated. The authors think that the mercury pollution is not only from the man made pollution sources, but also from the release of Hg steaminess in the earth.
