The Application And Study Of Electrical Method On Wulan Volcano Hydrothermal Type Deposit Prospecting In Wulan, Inner Mongolia

Increase the mining area known deep and periphery of concealed orebodiesexploration efforts, is the subject of a new round of prospecting exploration trend. Thisthesis research were ulam lead-zinc deposit in Inner Mongolia silver known orebody deepand periphery of electric prospecting, predict the deposit is deep and periphery prospectingpotential if it has.Wulan Lead-Zinc-Silver deposit is subvolcanic hydrothermal Lead-Zinc-Silver depositlocated in Hargentai Town of Xi Ujimqin in Inner Mongolia. The geological background inthe southern segment of the Da Hinggan Mountains, containing rich Pb Zn Ag Sn Cupolymetallic mineral, metallogenesis associated with sructural-agmatic activity of msozoic.The feature of Wulan subvolcanic hydrothermal Lead-Zinc-Silver deposit is controlled byfaults, the orebodies themselves are mostly vein, lens-type or banded in shape. The ore ofSubvolcanic hydrothermal Lead-Zinc-Silver deposit are disseminated galena， sphalerite，pyrite and magnetic pyrite.The subvolcanic hydrothermal type lead-zinc deposit is a silver polymetallic deposit inone of the main types, electrical method in the exploration of ore deposit is looking for thistype of a kind of effective prospecting method. In domestic and abroad typical subvolcanichydrothermal type lead-zinc ore deposit geology characteristics, the earth silver physicalcharacteristics based on the analysis, this paper summarizes the zinc silver deposits wereulam magmatic rocks, the structure, strata, orebody characteristics, geophysicalcharacteristics, research in the area of the electric prospecting in the geological, geophysicalprerequisite.In the working area of electricity in through the ladder sweep measurement，Circle ofD1DJ and D2DJ two groups of seven abnormalities. were marked by features ofore-generating anomaly and the anomalous features are obvious, outlines are regular,distribution ranges are large, and centers are clear. The anomalies are relative to surfaceauriferous pyritization belt and reflecte features of gold ore-formation or ore body. TheD2DJ-2、D2DJ-3anomaly features are obvious, outlines are regular, distribution ranges arelarge. The anomaly relative to Ⅰ、Ⅱorebody, according IP sounding method, find D2DJ-2anomaly has deep prospecting potential. That is the deposit is small and medium-sized preliminary silver lead-zinc ore prospecting potential, exploration results can provide thebasis for further engineering verification.
