德兴铜矿大山选厂碎矿系统分析与技术改造 - Geology and origin of tongchang gold deposit in yunnan province
云南金平铜厂金矿床地质特征和成矿物质来源 - ( 4 ) the trace elements and ree geochemistry of the tongchang granodiorite porphyry indicate , there exists the reaction between the porphyry and the hydrothermal fluid . the hydrothermal fluid was cl - enriched solution , and flowed from the porphyry center to contact zone
( 4 )德兴铜厂斑岩体微量元素和稀土元素地球化学特征表明，该岩体发生了流体?熔体作用，分异出来的流体是一种相对富氯的流体，同时成矿流体的流向是从岩体中心向接触带方向流动。 - 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。
