Abstract: It is considered that deposition to seam from marina and shallow marine is material foundation, and regional metamorphism for formation of shallow seam provides external conditions through the analysis of Helan quarry geological characteristics and evolution processes. The ore-body is in Huangqikou group strata, Middle Proterozoic Changcheng System,which is mainly composed of quartzite, quartz sandstone, sandy-slate and silt-slate. Lithology is silty（sandy） argillite, the original rock littoral-... More
