| 摘 要： | 根据盐盆的演化历史，水化学组分Ｈ，Ｏ，Ｓ，Ｂ等同位素组成综合分析，该浓卤水具有海，陆相混合型卤水的特征，一些元素的富集是在成盐成卤晚期由外来卤水和地层水流入盐盆混合并溶解盐层，在蒸发条件下形成的。

| Abstract: | The validity and its metallogenic implications of the extremely hydrothermal metasomatized auriferous ores RbSr isochron was carried out for the first time in Altai,Xinjiang.The results indicated that the RbSr isochron was of unambiguous significance under the following circumstances,(1)no epidote_bearing alteration assemblages(quartz±chlorite±sericite±albite,etc)were developed;(2)strongly altered(degree of pyritization greater than 70%)and(3)the initial strontium isotope ratio was homogenized.This'll be an alternative potential way to date the ore_forming related geological event and constrain the ore deposit genesis model. |
