【摘要】 金顶铅锌矿床流体包裹体的显微测温和微量元素特征表明:金顶矿区成矿流体均一温度为54℃~309℃,平均143℃,w(N aC l)为1.6~18.0,平均6.0,并且从矿区的东部向西部,由北部向南部温度逐渐降低,而盐度从东部向西部稍有降低,但是从北部向南部却是增加的;从第一矿化阶段到第三矿化阶段,成矿流体微量元素的种类、数量以及总量都是逐步增加的。更多还原

【Abstract】 The measurement of temperature of fluid inclusions in Jinding lead-zinc deposit shows that homogenization temperature of ore-forming fluid is at 54 ℃~309 ℃ and 143 ℃ in average,and its salinity is at 1.6%~18.0%(NaCl) and 6.0%(NaCl) in average.The results suggest that temperature in the ore district decreases from east to west and from north to south,and salinity in the ore district decreases from east to west but increases from north to south.The trace element nature of fluid inclusions in Jinding lead-zinc deposit indicates that the quantity and gross of trace elements in ore-forming fluid step up from the first mineralization stage to the third one.更多还原
