贵州烂泥沟金矿5种苔藓植物的生物地球化学研究及生物探矿潜力分析

Biogeochemistry research and analysis of biology prospecting potential on five bryophytes in Lannigou gold deposit, Guizhou province

应用AAnalyst800原子吸收光谱仪对烂泥沟金矿5种苔藓植物进行了Au、Cu、Ca、Zn、Hg、Pb、Mg等7个元素的分析,这5种苔藓植物是细叶牛毛藓(Ditrichumpusillum(Hedw.)Hamp.)、珠藓(BartramiahallerianaHedw.)、四川湿地藓(Hyophilasetschwanica(Broth.)Hilp.)、长蒴藓(TrematodonlongicollisMichx.)和芽孢湿地藓(HyophilapropaguliferaBroth.)。利用富集系数和衬度系数进行分析,初步推测细叶牛毛藓可能对烂泥沟卡林型金矿有指示作用,珠藓和长蒴藓应该可以作为寻找铜矿的指示植物。

This paper analyzed the elements of Au ,Cu ,Ca,Zn,Hg,Pb and Mg of five bryophytes with Atomic Absorption Spectrophotometer （ A Analyst 800）. These bryophytes are Ditrichum pusillurn （ Hedw. ） Hamp. , Bartramia halleriana Hedw. , Hyophila setschwanica （Broth.） Hilp. , Trematodon longicollis Michx. , Hyophila propagulifera Broth. By analyzing the enrichment factor and contrast ratio, it is tentatively inferred that Ditrichum pusillum（ Hedw. ） Hamp. is an indicator plant for prospecting Carlin type gold ore in Lannigou, and Bartramia halleriana Hedw. and Trematodon longicollis Michx. as copper ore indicator plants.
