摘要
自然界中的成矿流体按其主要成分,可分为:(1)岩浆,即形成岩浆矿床的岩浆;(2)以H2O为主的流体(含Na Cl);(3)以CO2为主的流体。地壳中的流体类型很多,只有含一定金属元素含量的,并且达到一定浓度时才称为金属矿床的成矿流体。基于对矿床中流体包裹体和天然成矿流体中金属种类和含量的测定,这些金属矿床的成矿流体按金属元素含量可以分为五组,成矿流体可以来自岩浆、岩浆热液、大气降水、盆地卤水和变质流体等地质环境。
Ore forming hydrothermal fluids,consisting largely of silicate melt,H2O,CO2and NaCl,formed most of Earth＇s mineral deposits. The ore forming fluids exist as magma,magmatic fluids,meteoric water,seawater,basinal brine,and metamorphic fluids. The metal concentration of the ore forming fluids could be classified into 5 groups according to their geochemical features and metal amounts in the fluids. These were approved by the fluid inclusion and nature ore forming fluids analysis.
