摘要
平桂地区不同时代、不同层位、不同岩石中的元素组合和特征元素均有所不同;W在地层中具高背景值,Sn在地层中总的趋于贫化;地层是W的成矿物质来源之一,而Sn的成矿物质来源与地层无关。
The characteristics of stratum-geochemistry in Pinggui area aremainly distinguished as different element assemblages and model elem-ents among the different geologic ages, strata and rocks. According tostudy, W appears to be highly abundant, while Sn tends to be poor inlayers. It follows that the strata are one of the important sourcesof W and there is no relation between Sn sources and strata.
