摘要
在低温热液型矿床的形成过程中 ,生物和有机质发挥了重要的成矿作用 .这种作用可以归纳为直接和间接两种 .生物及有机质直接参与成矿作用的意义在于 :在沉积岩主岩的同生沉积阶段形成矿源层 ,在成矿物质活化迁移过程中形成含矿流体 ,在成矿元素的沉淀阶段富集形成矿床 ;生物及有机质间接成矿意义是指有机质的成熟演变作用及其产物可以揭示成矿过程 ,反映低温热液成矿机理和成矿条件 .
During the mineralization of the low temperature hydrothermal deposits, organisms and organic matters play an important metallogenic role deducted as two major categories: direct and indirect metallogenic roles. The direct metallogenic role of organisms and organic matters means the formation of source beds in the contemporaneous sedimentary stage, the formation of ore bearing fluids in the activation migration of mineralizing materials, and the formation of mineral deposits derived from the accumulation of mineralizing elements during the precipitation of mineralizing materials. The indirect metallogenic role refers to the fact that the maturation evolution of organic matters and relative organic products may reveal the mineralization process, reflecting the low temperature hydrothermal metallogenic mechanism and condition.
