生物地球化学找矿,是通过发现植物的地球化学异常,以确定基岩矿化情况的方法. 岩石、矿体(包括原生异常),由于表生风化作用,转变为风化产物(以矿物形式或非矿物形式存在),部分是可溶性的含氧酸盐,如硝酸盐、碳酸盐、硫酸盐、有机络合物等,为生长在该区的植物根系,无休止地选择性吸收;即使是难溶化合物,如硫化矿,也因为植物根系分泌的 Biogeochemical prospecting is a method of determining the mineralization of bedrock by identifying geochemical anomalies in the plant. Rocks, ore bodies (including primary anomalies), due to superficial weathering, are converted to weathering products (either in mineral form or Non-mineral forms), partly soluble in the presence of oxygenates, such as nitrates, carbonates, sulfates, organic complexes, etc., for the selective uptake of plant roots growing in this area; even Poorly soluble compounds, such as sulfide ores, are also secreted by plant roots
