Mineral Deposit Exploration Model Of Cu-W Polymetallic And The Prediction Of Ore Prospecting Targets,in Zhuxi,Jiangxi

The Zhuxi Cu-W polymetallic deposit which lies in the northwest of the Dexing ore concentration and in the southeast of the Jiurui ore concentration is located in Jingdezhen city,JiangXi Province.Under the control of the Taqian-fuchun thrust fault and the fault basin,this area boasts advantageous geological conditions of the Ore-forming.Having done a great deal of work,people've found lots of ore deposits,most of which are under miniature.Therefore,it is imperative to carry out deep prospecting within the study area.To achieve this deep prospecting,we must strengthen the research of the metallogenic theory and prospecting model.Based on the analysis of metallogenic systems as well as the previous researches,this paper aims to the explore the model of the Zhuxi ore deposit and the general law of the metallogenic with the effective methods provided by the geophysical-geochemical-remote sensing exploration.The specific details of the work and results are as follows:(1)Concluding the geological features by studying the geographic datum in systematic way.Concluding the geophysical anomalous character by the analysis of aeromagnetic anomaly and gravity anomaly and the physical property measurement in the main geological unit.Concluding and studying the general law of the ore-forming elements by the distribution of the geochemical anomaly.Extracting the information of alteration and the structure linear of images existed in the remote sensing images of the Zhuxi area.(2)Concluding the prospecting criteria of the deposit systematically:(1)Geology:The main indicator of ore-controlling lies in the northeastward faulted structure formed in Yanshannian.Biotite Granite,Granite Porphyry and Alteration Granite are the main ore-bearing intrusive.The stratigraphic marker is Permo-Carboniferous carbonate rock.(2)Geophysics: The general characteristic of the geophysical field of the ore-bearing rock in this area is of medium-low resistance,low gravity,medium-high polarization,high magnetic and high rate change of both electrical resistivity and polarizability.Aermagnetic anomaly is lower positive magnetic anomaly.(3)Geochemistry: stream sediment,rock andsoil anomaly is similar to the assemble anomaly of W?Cu?Mo?Pb?Zn?Ag?Au.(4)Remote sensing geology information: The remote sensing anomalies manifests the large area of the anomaly of the hydroxyl and iron-stain mineralized and the information of the alteration and the structure liner of the images.(3)Having synthesized the relevant information of geology,geophysics,the anomalous character of the geochemistry and the remote sensing images,the author has established the exploration model of Zhuxi ore deposit,conducted the metallogenic prognosis and prospected two target areas which can be explored and evaluated:Zhuxi-Huangtukeng and Tangwu-Tangling prospecting prospect forecast areas.This paper can be guided to search ore in both deep and peripheral,even to search and predict the ore with the same ore-deposits.
