摘 要:以湘西金矿外围(东部)脉石英为例,研究了包裹体的气、液相成分特点,提出包裹体中的CO2,HCO3-,CO2/H2O,HCO3/Cl-离子总浓度(ΣI)可作为评价石英脉含金性的标志,并总结出石英脉含金性评价的矿物学特性,预测了外围四个工作小区的成矿远景。
Abstract: By using the vein quartz from the periphery of Xiangxi Gold Deposit (ea-stern part) as an example, the paper has researched into the composition features of its gas-liquid inclusion, and put forward a new idea that the CO2 or HCO3- content, the value of CO2/H2O or HCO3/Cl-,and the total amount of ion concentration (∑I) in quartz inclusion could be used as the signs for gold evaluation. Moreover, the paper has also summed up the mineralogical signs for gold evaluation of quartz vein, and predicted the deposit-forming prospect of the four branch working regions.
