摘要
随着供给改革的不断推进,我国对矿产资源的需求不断的增加。根据上述背景,提出金属矿床成矿流体物理条件分析。首先对成矿流体温度进行分析,经过研究发现金属矿床成矿流体的温度主要在200℃～300℃区间之间;其次对成矿流体盐度进行分析,经过研究发现金属矿床成矿流体属于低盐度体系,其盐度的主要分布范围为1%～3%区间之间;最后对成矿流体密度与压力进行分析,发现金属矿床成矿流体的密度分布为0.7 g/cm^3～0.9g/cm^3,捕获压力范围为38 KPa～68KPa。
With the continuous development of the supply side reform,the demand for mineral resources has been increasing.Based on the background aboved,the physical conditions of metallogenic fluid in metal deposits are analyzed.Firstly,the temperature of ore-forming fluid is analyzed,and it is found that the temperature of ore-forming fluid mainly range form 200℃~300℃.Secondly,the salinity of ore-forming fluid is analyzed.The density and pressure of ore fluid were analyzed.It was found that the density distribution of ore-forming fluid was0.7 g/cm3~0.9g/cm3,and the trapping pressure was 38 KPa^68KPa.
