摘要
湘西北寒武、奥陶系中的古硅华硅质岩的地理分布、形态产状、矿物成分、结构构造、形成环境及地球化学特征分析表明 ,其成因应属第三纪的古硅华。从其地质地球化学特征及与之有关的矿产看 ,这类古硅华是寻找浅成低温热液矿床的重要标志。
The ancient tufas which occurred in Cambrian and Ordovician system in northwest Hunan should be formed in Tertiary from their geographic distribution, form and attitude, mineral component, texture and structure, environment-formed, and geochemic characteristics The non-organisms ancient tufa or alteration one is the important indicator for epithermal deposits from its geologic and geochemic characteristics and the mineral resources that are interrelated with it
