Abstract
Dongyaozhuang gold mine is a typical deposit of greenstone belt gold mine in Mount Wutai mountain.The ore body mainly exists in the long schist formation of Hongmen Formation,and the ore body is controlled by the toughness shear zone.The deposit is of metamorphic hydrothermal type,and the alteration related to metamorphic hydrothermal mainly includes potash,pyrization,carbonization and silification,followed by natritization,sericite,chlorite and electrical petrochemical.The main ore types are pyritic sodium long schist and pyrified silicate sodium sericite long schist.The geophysical characteristics of the mining area show obvious polarisation difference between ore and surrounding rock,which is divided into two parts based on 2.0%contour coil,numbered as JD1 and JD2;there is obvious resistivity difference between surrounding rock and the northwest region is a low resistance distribution area,with high resistance and high resistance anomaly in the southwest.Through the drilling verification study in the abnormal area,the high visual polarization rate and low visual resistivity in the abnormal area of JD1 are good;the abnormal high visual polarization value and high visual resistivity in JD2 are poor.The exciting abnormal area has a guiding role in the prospecting work of Dongyaozhuang gold mine,and the geophysical abnormal area can be determined as the prospecting area.关键词
