摘要
In the Western Hunan and Eastern Guizhou Provinces, the Lower Cambrian is well developed and marked by sedimentary succession from black shale to carbonate rocks. The stratabound lead-zinc deposits distributing between platform marginal facies and subtidal facies of restricted carbonate platform were dominated by the lithofacies palaeogeographic framework. The black shale of the Niutitang Formation is source bed for the lead-zinc mineralization and the Qingxudong Formation is the host rock (reservoir bed). The assemblage that made up of turbidite and algal bioherm (reef) and rudstone is a well developed succession for the lead-zinc deposits controlling.
