The Geological Significance of the Estremely Hydrothermal Metasomatized Auriferous Ore Rb-Sr Isochron
川西成都盐盆平落4井富钾硼溴浓卤水水化学同位素地球化学特征及形成机制

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.
