Characteristics And Genesis Of The Ergenhe Glod Deposit In Mohe County,Heilongjiang Province

The study area is located in Ergenhe Gold Mine,Mohe County,and the geodetic structure is located on the south side of the Mongolia-Okhotsk tectonic activity belt,on the north edge of the Erguna.The tectonic volcanic eruption belt is located in the northeast direction of the Eastern Tianshan-Jiaolu Mountain in the Heilongjiang Sag.Also,located on the middle of cooper and gold metallogenic belt of Shabaosi-ErgenheTwenty-one Station.This work mainly carries out research on the geological characteristics of the Ergenhe Gold Mine.The geological,geophysical and geochemical characteristics of the deposit have been ascertained by means of geochemical prospecting,high-precision magnetic method and induced polarization medium elevator.on this basis,by combing the research results of predecessors to discuss the source of ore-forming materials,and then we are believed that ore-forming materials are mainly derived from mantle and with a small amount of crustal material.Besides,conducting a comparative research among the Shabaosi Gold Mine and the Laogou Gold Mine in the adjacent area,The commonness and characteristecs of Ergenhe deposit and Shabosi deposit are obtained.The sulfur isotope and carbon dioxide fluid inclusion are studied.The metallogenic temperature and conditions of Ergenhe deposit are analyzed.then it has determined that the genetic type of the Ergenhe Gold Mine is an orogenic gold mine.
