The Study Of Copper And Gold Geological Characteristics And Genesis In Duo Bao Shan Area, Heilongjiang Province

Study area is located in northern Heilongjiang province, mainly in the area ofmineral Duobaoshan-Kuanhe ring structural belt. Copper, Molybdenum and othernon-ferrous minerals are located in the island arc (ring) structure belt. Gold deposits(mines) are mainly distributed in diamond fault zone. The study area has been foundvarious types of deposits14points and multiple mining, mineral. There exists quitecomplete sedimentary sequence consisting of Paleozoic and Mesozoic formation. Thestudy area’s tectonic position include Tianshan-Xingmeng orogenic Daxinanling fold beltwith excellent Xiaoxing’anling geosynclinal uplift coupling parts Duobaoshan island arcbelt in the north side of the arc basin and Daxinganling Huma magmatic belt, south of theBlack River tectonic melange and Xiaoxing’anling-Zhangguangcailing magmatic beltnorthwest section. Intrusive rocks are well developed and distributed extensively. Theyhave a certain relation with a clear multi-phase, multi-stage, space zonal distributionsignificantly. Intrusive rocks in the time period can be divided, Proterozoic, Caledonian,Variscan, Indosinian, Yanshan five intrusive cycle. Indosinian and Yanshanian intrusivecycle is the most developed. Variscan and Yanshanian small intrusive bodies are close tomineralization of porphyry copper–molybdenum-gold deposit and gold deposit is of ahydrothermal fluid filling quartz vein–type.This paper analyzes the regional metallogenic regularity study area. This paper will be divided into two regional metallogenic large main mineralization stage, Late Paleozoiccopper-gold polymetallic mineralization period, Mesozoic gold polymetallicmineralization stage. This division is based on the different geological stages of the studyarea, the different geological units in a variety of spatial and temporal distribution ofmineral and material composition variation metallogenic characteristics. And this paperanalyzes the various types of minerals, size and characteristics of the two majormineralization stage.Meanwhile the study area typical porphyry copper, gold and copper skarn andepithermal gold deposit characteristics were analyzed. Through the study area moretypical deposit geological characteristics and ore-controlling geological conditions, as wellas physical, geochemical and remote sensing data analysis, the district gold-brass bedspace output form, mineralization and genesis of the law have a preliminaryunderstanding.Study area generally in the N-E gold mineralization and N-W copper, molybdenum,gold metallogenic belt cross area. This region has long history of development, complexgeological structure, widespread sedimentary strata, and in this area magmatic activity isfrequent. Mineral resources of the region are mainly copper and gold. This area constitutesan important space on NE Silver Gold Tungsten Molybdenum copper and iron ore belt.Therefore, this area has great potential mineralization and find large and find largedeposits is possible.
