宾川幔坳区斑岩铜矿综合信息三维找矿模型 - Chen p . r . , chen x . m . , ni p . , wang w . c . et al . , 1997 , discovery of chalcopyrite daughter mineral in polyphase fluid inclusions from yanyuan porphyry copper deposit , sichuan province
朱金初，李人科，周凤英，王汝成等， 1996 ,广西栗木水溪庙不对称层状伟晶岩?细晶岩岩脉的成因讨论。 - Log ( fh2o / fhcl ) fluid and log ( fhf / fhcl ) fluid ) , tongchang porphyry copper deposit system is enriched in chlorine , however dajishan tungsten deposit system is relatively enriched in fluorine , which transport w , sn , nb , ta , et al . ( 8 ) according to the characters of the porphyry copper deposits , copper is transported by chlorine , such as cucl0 and cucl2
忍l ) flu ， d 、 109 ( / hr州el ) fluid )发现，铜厂斑岩型铜矿床的成矿体系是相对富氯体系，而大吉山石英脉型钨矿床成矿体系相对富氟，同时氟可能主要迁移w 、 sn 、 nb 、 ta等金属元素。 - Cl , s , f , tongchang porphyry copper deposit and the dajishan tungsten deposit are selected as the studying objectives , detailed investigations have been conducted into the geological and geochemical characteristics of the granitic rock , biotite , trace element and ree geochemistry , fluid inclusion geochemistry and the partitioning coefficients of the f , cl , cu , w . based on these data , the following conclusions are drawn : ( 1 ) fluorine can reduce the viscosity and density of magma , temperature of solide - liquidus line and change the melt frame , but cl has little effect on the melt
主要的认识如下： ( 1 ) f在花岗质岩浆中，可以降低岩浆的粘度、密度、固液相线温度、改变熔体结构，而cl对熔体结构没有多大的影响。 f在流体?花岗质熔体相间，绝大多数配分系数小于1 . 0 ，趋向于熔体相中配分， d _ f随体系中f浓度的升高而增加。 - Finally , the fluid inclusion characteristics of yinshan deposit is compared with the typical fluid - inclusion characteristics in ore formation model of porphyry copper deposit . the ore - forming fluid of yinshan deposit share certain similarities in the evolution of ore - forming fluids with porphyry copper deposits , which indicates a genetic link between the yinshan polymetallic ore deposit and porphyry copper deposit in the depth of the deposit . it is concluded that yinshan deposit is refereed to " transitional deposit " between the porphyry copper deposits and epithermal deposits
最后，将银山矿床流体包裹体特征与sillitoe提出的斑岩铜矿成矿模式进行对比得出，银山矿床的成矿流体与斑岩铜矿的成矿流体具有特征的相似性和成矿演化的继承性，认为它是一个联结深部斑岩铜矿和浅部浅成热液矿床的“过渡型矿床” ，矿床深部可能隐伏有斑岩铜矿床。
