The Metallogenic Conditions And Prospecting Prediction Of Cu-Pb-Zn Polymetallic Deposit In Budayuan Area Of Kuandian County,Liaoning Province

The study area Kuandianbudayuan located in the junction of the paleoproterozoic Liaoji rift Kuandian,Yingkou-Kuandian phanerozoic uplift and taizihe-hunjiang depression in the eastern part of north China;It is an important mineralized area of Pb,Zn,Cu and Au in the NW substructure zone between the Yalu river and Taiping shao deep faults.Less studied work in this area,In order to further to find out the research areas of mineral resources,expand the prospects,By extracting the comprehensive information of regional geology,geophysical exploration,geochemical exploration and mineral resources,this paper analyzes and studies the information of geology,geochemical exploration,geophysical exploration and mineralization in the research area.Selected high-quality metallogenic prospect areas,to step up to indicate the direction for future exploration in this area.The strata in the study area include Gaixian formation of Liaohe group in the lower proterozoic,Diaoyutai formation,Nanfen formation and Qiaotou formation of Qingbaikou system in the upper proterozoic,cambrian and cretaceous Xiaoling formation in the Paleozoic,and Gaixian formation of Liaohe group in the proterozoic with relatively high content of metallogenic elements such as copper,Pb,Zn and gold.Cambrian is an important ore-bearing horizon of copper,lead and zinc in the region,in which copper,lead and zinc are 4 to 8 times higher than the crustal clark value.This double-layer "ore source" provides a large number of material sources for mineralization in this region.The Budayuan rock mass is developed in the study area,the Tandianzi rock mass is developed in the north and west of the study area,and the stone pillar rock mass is developed in the south of the study area,which provides the source of metallogenic materials and thermal power for the formation of Cu,Pb and Zn ores,and also controls the spatial distribution of ore bodies.The fold structure in the study area is Guanmenlazi-Huangjiajie syncline,fracture structure mainly include the north east,north west nearly north-south and nearly east-west fault,the fault cutting cross each other,for the formation of Pb,Zn,Cu deposit,providing favorable space fault controlled the area of Cu,Pb,Zn ore bed.Based on the processing,analysis and study of 1:50,000 river system sediments and 1:10,000 soil geochemical data in the study area,according to the geological environment and the characteristics of ore-forming elements in combination with the anomaly characteristics of the dispersed flow area,comprehensive anomaly zone in the circle area were separated seven and four assumes the planar distribution of anomalous clusters.The abnormal area is favorable for Pb,Zn,Cu ore.Based on the study area and its nearby measuring and analysis of the physical parameters of the rock,determine the low resistivity and high chargeability anomaly in the important prospecting marks for the area.By analyzing and summarizing the geological and geophysical information,as well as the study area of geological conditions,geochemical and geophysical conditions and mineral information extraction and analysis,this article altogether circle 4 Pb,Zn,Cu metallogenic prospect areas,one ? metallogenic prospect areas,two ? metallogenic prospective areas and one ? metallogenic prospect areas.Combined with the evaluation of the prospecting potential of the prospective area,the Zn prospecting targets of Chatiaogou were finally selected as the prospecting target areas.
