| Abstract: | 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 |
