摘要
以湖南湘西金矿及其外围(东部)脉石英为例,研究了脉石英包裹体的气、液相成分特点,提出包裹体中的CO2、HCO-3、CO2/H2O、HCO-3/Cl-及离子总浓度(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征,预测了湘西金矿外围四个工作区的成矿远景。
By using the vein quartz from the periphery of Xiangxi Gold Deposit (eastern part) as an example, the paper has researched into the composition features of its gasliquid inclusion, and put forward a new idea that the CO2 or HCO-3 content, the value of CO2/H2O or HCO-3/ Cl-,and the total amount of evaluation (ΣI) 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 quart vein, and predicted the depositforming prospect of the four branch working regions.
