试论岩浆-热液流体聚焦中的成矿效率
Metallogenic efficiency associated with the magmatic hydrothermal fluid-focusing process
摘要
Abstract
As magmatic-hydrothermal ore deposit was centered by the granitic pluton,in the convection of oremaking fluids there are two opposite effects correspondingly:integrated and dispersive flows.Fluidic Integration might trigger a non-linear mechanism and might be accompanied by an accumulation of mineralizing materials,generating ore reserves eventually.Hydrothermal alteration caused by fluid-dispersing flow results in a scatter of metallic mass instead,which can be easily detected by remote sensing or geochemical data because of its wider distribution.In this way,the ratio of metal tends to fluidic total supply of metal,a summation reserve and metal mass dispersed into wallrocks can be defmed as the mineralized efficiency,in order to reflect the ore-productivity of a given geological body.The essential proposition in metallogeny,the idea of ore efficiency may be expected as a crucial role in metallogenic regularity and prediction.关键词
