雪峰地区金矿成矿时代问题的探讨

在对平茶、肖家金矿进行流体包裹体同位素测年的基础上，结合最新的一批测年数据，认为雪峰地区金成矿带的成矿时代并非传统认识中的武陵—雪峰期（１０００Ｍａ～８０００Ｍａ），而是形成于加里东早期以后；加里东、印支—燕山期是雪峰地区两个主要的金成矿期，特别是印支—燕山期地台活化对该区大型金矿的形成起着重要作用。在此基础上，对当前流行的一些观点进行了初步探讨。

ON THE MINERALIZATION EPOCH OF THE XUEFENG GOLD METALLOGENIC PROVINCE

Based on the age determination of the Pingcha, Xiaojia gold deposits,Southwestern Hunan,together with the age data newly published, it is proposed that the mineralization epoch of Xuefeng gold metallogenic province isn't Wuling-Xuefeng epoch as common concerned, but Caledonian epoch and Indo-Chinese-Yanshanian epoch, especially the Indo-Chinese-Yanshanian platform activation plays an important role in the formation of large-scaled gold deposits in this gold metallogenic province.In addition to the above mentioned,some related opinions are discussed.
