Analysis on the prospecting potentiality in Bailanggou mineralized region, Sunan, Gansu Province

Bailanggou mineralized region is located in the Ordovician back-arc basin volcanic rock belt along the west sectoin of North Qilian Mountains.The pelovolcanic edifice is storaged effectely.The volcanic rock belongs to the upper part of the opholite suite, the volcanic lithofacies developed entirely and the exhalite related copper mineralitation-red jasper is developed abroadly.The copper mineralitation is found in the pelovolcanic edifice every where.They are divided into two kinds, one is related with tectonic crushing belt, the other is the volicanic massive sulfide metallization related with submarine hydrothermal-solution spouting.It shows that there is quite large potential capacity of prospecting rich-copper volicanic massive sulfide deposits in the region.
