蓝藻富集金的模拟实验及其地质意义

SIMULATING EXPERIMENTS ON THE PROCESS OF ACCUMULATION OF GOLD BY BLUE ALGAE

通过对华南寒武纪古地理环境的分析,并结合蓝藻富集金的模拟实验,论述了蓝藻富集金及其生物化学沉淀金,为该区含金建造的形成提供了金的主要来源,最后阐述了华南寒武系黑色岩系含金建造的形成机制。

Some experiments on the accumulation of gold by blue algae have been made to simulate theconditions prevailing in the Cambrian paleogeographical environments in southern China. Resultsof the experiments show that the accumulation of gold by blue algae or the biochemical preci-pitation of gold from sea water may be responsible for the auniferous formations in the Cam-brian gold-bearing black rock series in this area.
