摘要
通过对小秦岭金矿田四个典型矿床成矿温压条件和成矿溶液的成分、酸碱度、硫逸度等物理化学条件的分析研究,得出如下结论：①主要成矿温度296℃-155℃,属中、低温矿床;②成矿压力108-163MPa,为成矿压力范围;③硫逸度随矿化阶段不同而变化;成矿pH值6左右。确定矿床形成的各项物化条件下,扩大了地质找矿方面信息量。
Based on a study of ore-forming temperature,pressure and composition,pH,sulfur fugacity of ore-forming solution of four typical deposits in Xiaoqinling gold field,the following conclusions can be drawn： 1） The main ore-forming temperature is 296~155℃,which are medium-low temperature deposits;2） The ore-forming pressure range is 108~163MPa;3） Sulfur fugacity varies with the mineralization stage.The pH value of ore forming is 6.The geological prospecting information are expanded under determining the physico-chemical conditions of the deposit formation.
