Metallogenic Prognosis Of Lead-Zinc-Stibium Polymetallic Deposit In Sangrize,Tibet

Sangrize the antimony lead-zinc polymetallic deposit is located in the north wing of slipping wrong with that hole core complex,the paper on the basis of metallogenic geologic condition of the study area and the distribution of the known ore body on the combination process using a variety of methods in the study area geochemical data,test data phase,and extract the geochemical anomalies associated with mineralization,hydrothermal alteration information display,geological,existing methods test data analysis,comprehensive metallogenic prediction,We reached the following understanding:(1)Sangrize the lead-zinc deposit is located in the north wing of the wrong that hole metamorphic core complexes with spondylolisthesis,the main structural styles for the scabbard fold,cyclic mylonite zone and joint intensive band;(2)control the main mining area Coal mine in north-south direction with dense joints,scabbard fold,level;(3)major mining ore rock calcareous rock;(4)zone structure,frequent magmatic hydrothermal alteration strongly,mainly as a suicide,silk of mica,chlorite and so on.Was surface-type alteration,alteration features complex.(5)the 1/5 one thousand IP intermediate gradient,1 / 50,000 ground precision magnetic survey,1 / 10,000 geochemistry,1 / 10,000 X diffraction phase analysis of the effectiveness of the method adopted.Summed up one thousand IP intermediate gradient 1/5,1 / 50,000 ground precision magnetic survey can not guide this Wanda 1/1 scale metallogenic prediction.1/1 Wan leading edge geochemical halo(Ag,As,Sb)+ Central halo(Cu,Pb,Zn)+ tail Halo(W,Sn,Mo)+ anion halo(S,Se,Te)+ mineralization agents(Cl,F,B)integrated anomaly,1 / 10,000 X-ray diffraction encircled by hydrothermal alteration minerals(actinolite,sericite,rutile,chlorite,smectite)superimposed abnormal area can be used as an integrated prospecting method elements.(6)Sangri the antimony lead-zinc Deposit in good condition,according to the geological metallogenic features and prospecting methods determined by factors delineated and preferably a six prospecting targets Class A,Class B three prospecting targets.
