The Baiyinhaer gold deposit is a typical gold—bearing qua~z veins type and gold—beating altered rock type omposite gold deposit in polymetallic ore belt of the northern margin of North China Craton．On the basis of high—reso—lution geological mapping，measurement and study of tectonics，analysis 0f geochemistry Of Au，As，Ag，Cu，Pb，Zn，Bind 0ther elements．We consider that the distribution of the ore—veins of the Baiyinhaer gold deposit is controlled by he fracture zones of the NE．NNE and EW strike．The mineralization of the Baiyinhaer gold deposit is a product of SU—
perposition of gold multi—stated mineralization．which is bound up with the intermediate—acid intrusive rocks in the area．The ore—forming materials of quaaz veins type of gold—bearing ore mainly come from the Group Rocks of the Middle nd Upper Proterozoic Erathem．while the 0re—forming materials of altered rock type of gold—bearing ore mainly come rom the qua~z—diorite and plagiogranite~rmed in late Variscan Age in the area．
According to regional geological background and geochemistry of antimony gold occun-ence in Longte，
coin．bined with its orebody characteristics and ore type，comparison and analysis for mining area and its surrounding strata，structural feature，conditions of magmatic hydrothermal and geochemical characteristics．Analyse the antimony gold OC—cuence and its prospecting potential in Longte
Eerqisi gold zone is relatively advantaged to gold ore—formation and mixed metal ore—formation．In devonian nd carboniferous，volcanic—clastic strata startigraphy are the primal7 auriferous strata． Variscan intermediate—acidicmagatic rock and overgrown volcanic belt provide metallogenic condition and hot source for enrichment of gold and opper．area coverage north to west，north to west to west direction’S fracture control the gold mine in distinct deree． Especially．area coverage slanting—stride fracture is more evident．Prospecting has fracture mine—controling characteristics，give attention to the application of other mine—controling factors．
In recent years，we obtained many up to date exploration data about census stage and sifting stage in Shabaosi diggings．We researched the status of groundwater in this region，analyzed the characteristics and water yield property about this diggings and studying of the ore—bed．This will be helpful to the future geological survey efforts．
Locating in the center of the Jiamusi block，the Shuanyashan gold mine is a typical skarn deposit．Geologic data from exploration and mining demonstrated that the distribution of deposit bodies is strongly controlled by skamization and fracturing．Gold—content analyses of the country rocks indicated that the gold element resourced from migmatization of basic—andesitic volcanic rocks．The migmatic fluid，which contained higher Au—complex—compound，flows along fractures or bedding faces．When contacted with carbonatite，skarnization occulted decreasing the pH value of
the Au—bearing fluid，leading the gold depositing from the Au—complex．The major Au—bearing mineral is Al~enopyrite(FeAsS)with minor other sulfides，suggesting the complex anion of the Au—complex may be[AsS3]．
Xilaokou gold deposit is located in the northern edge of Jiaolai basin．The main strata are Paleoproterozoic Jingshan Group and Mesozoic Laiyang Group．Magma activity of Yanshan Period is the main．Th e structures relates to gold mineralization are complex．Surface mineralization and alteration can be f0und everywhere．it makes ore—prospecring dificult． By summarizing the geological feature of this area，The regional stru cture relates to gold mineralization can be divided into two types，namely interstratified sliding structure belt and tensile fracture belt of upper plate．The
ore—prospecting thinking is put in good order．Discussion on future exploration is carried out．
The Baoxinggou gold ore is located in the Tahe River transition in southeast border of Eerguna massif，in geosyncline folded belt from Daxinanling to Inner Mongolia geosyncline， in the intersection of southern fringe of Yaozhan fault depression which is depressed and north margin of Shibazhan uplift．At present，we have discovered two mineralization alteration belts and five stave alteration crag gold ore bodies in the mining area．Three gold ore bodies have been discovered in Au—HT07—3 anomaly，average gold grade is 1．84×10 ．highest is 6．43×10-6． Mineralization condition in this region is advantageous，and it also has a good prospecting prospect
Wudaoling molybdenum deposit is a large skarn molybdenum ore- bed found in Acheng，Heilongjiang Province ．The alkaline gmnites at Indo Chinese epoch supplied some 0re—formation materia1 and the granitoid emplacementin Permian pmvided heat resourse，ore eading sPace and。reholding space．Alkaline granites and PYrite aplite which is ahered IDck in the marginal facies of alkaline granites are important fact0r of 0re-formarl0n．And we can ofer war rant fl0r finding the same type ore bed in this region on the basis of studying alkaline granites at Indo-Chinese epoch in W udaoling formation．
the crust area of Sishan forestry centre became active strongly in Upper Triassic and a rupture be formed· with v0lcan and intmde of magma，the Sishan copper mine is produced in the belt’area that make up of Paleo-Proter -ozoic Yanwangdian group stratum and Jurassic diorite which corroded，it average content is 0·45％. the body of mine is prduced as layer or approximately，it is a porphyry types and a medium mine with a lower quality·
Wudaogou gold deposit exists in Yanwangdian formation in Huangsong group of Upper Proterozoic. On the basis of analyzing geological features of the deposit, it can be seen that Yanwangdian formation in Huangsong group of Upper Proterozoic is the source bed, north to east structure provides the channel for magma`s invasion and forming a better ore-leading space and ore-hosting space. On the basis, it can be concluded the ore-prospecting and established the prospecting moldel.
