坎塔布连山脉地区的南部金矿区中,进行生物化学找金时,系统地采集了Festuca ovina L.(Gramineae)和Chamaespartium tridentatum(L.)P.Gibbs.sub.sp.cantabricum(Spach.)Riv-Mart.,Izco和Costa(Leguminosae)的干树叶子,并用中子活化分析方法分析了样品中的金、砷、锑。尽管这两种植物都指示了同一个金矿区,但用F.ovina反应的异常比用C.tridentatum更明显。一条试验性剖面的测量结果表明,植物中金含量与土壤中金含量是一致的。积累频率数据用来评价地球化学异常区,得出的结论是:在该地球化学成矿省内,用生物地球化学方法找金是可行的。
Festuca ovina L. (Gramineae) and Chamaespartium tridentatum (L.) P. Gibbs.sub.sp.cantabricum (Spach.) Were systematically collected for biochemical gold search in southern gold mines in the Cantabrian Mountains. ) Dried leaves of Riv-Mart., Izco and Costa (Leguminosae), and analyzed for gold, arsenic and antimony by neutron activation analysis. Although both plants indicate the same gold area, the anomalous response with F.ovina is more pronounced than with C.tridentatum. The results of a pilot section show that the gold content in the plant is consistent with the gold content in the soil. Accumulating frequency data is used to evaluate the geochemical anomaly area and concludes that it is feasible to use biogeochemical methods to find gold in this geochemical mineralization province.
