| 摘 要： | 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。

| Abstract: | Based on exemplification of Anqi
metallogenic fault in western Junggar,the present paper has briefly discussed the
application of biogeochemistry in gold deposit exploration in detail,including the choice
and collection of the plant samples,the analysis steps,and their influence factors.Anqi
metallogenic fault is located in western Junggar of Xinjiang,adjacent to Kazakhstan,lying
in north limb of Dalabute synclinorium of in Junggar Hercynian folding belt.We have
collected the gold carrier plants,such as equisetales,mugwort or artemisia,and allium
bakeri,along the fault.Biogeochemical survey results show that the biogeochemical
anomalies of As,Au matched the metallogenic zones very well,some unknowing gold deposits
have been found.Biogeochemical method is a useful method in gold deposit exploration in
dry and half-dry climate belts. |
