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 ）發現，銅廠斑巖型銅礦床的成礦體系是相對富氯體系，而大吉山石英脈型鎢礦床成礦體系相對富氟，同時氟可能主要遷移w 、 sn 、 nb 、 ta等金屬元素。 -
Geology and origin of tongchang gold deposit in yunnan province
雲南金平銅廠金礦床地質特徵和成礦物質來源 -
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
主要的認識如下： （ 1 ） f在花崗質巖漿中，可以降低巖漿的粘度、密度、固液相線溫度、改變熔體結構，而cl對熔體結構沒有多大的影響。 f在流體?花崗質熔體相間，絕大多數配分系數小於1 . 0 ，趨向于熔體相中配分， d _ f隨體系中f濃度的升高而增加。 -
( 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 ）德興銅廠斑巖體微量元素和稀土元素地球化學特徵表明，該巖體發生了流體?熔體作用，分異出來的流體是一種相對富氯的流體，同時成礦流體的流向是從巖體中心向接觸帶方向流動。
