生物地球化学方法与金矿找矿--以新疆西准噶尔安齐成矿断裂带为例

以新疆西准噶尔安齐成矿断裂带的生物地球化学测量工作为例，详细研究了生物地球化学找金法的样品选取，采集和分析过程及其影响因素，并对生物地球化学方法的实际找金效果进行了分析。实验表明，在干旱，半干旱地区，野薤、等是金的敏感载体植物，它们可以带来地下７０ｍ深处的地球化学信息，利用这些信息生物，可以有效地指导找矿。

APPLICATION OF BIOGEOCHEMISTRY IN GOLD DEPOSIT EXPLORATION AS EXEMPLIFIED BY ANQI METALLOGENIC FAULT IN WESTERN JUNGGAR

Based on exemplification of Anqimetallogenic fault in western Junggar,the present paper has briefly discussed theapplication of biogeochemistry in gold deposit exploration in detail,including the choiceand collection of the plant samples,the analysis steps,and their influence factors.Anqimetallogenic fault is located in western Junggar of Xinjiang,adjacent to Kazakhstan,lyingin north limb of Dalabute synclinorium of in Junggar Hercynian folding belt.We havecollected the gold carrier plants,such as equisetales,mugwort or artemisia,and alliumbakeri,along the fault.Biogeochemical survey results show that the biogeochemicalanomalies of As,Au matched the metallogenic zones very well,some unknowing gold depositshave been found.Biogeochemical method is a useful method in gold deposit exploration indry and half-dry climate belts.
