稀矿山式铜矿以落雪矿区稀矿山矿段最为典型，主要分布在因民落雪大乔地?稀矿山、滥山、磨子山，滥泥坪6 ? 4巷、白锡腊和拖布卡地区。 - The yinachang fe - cu - ree deposit is one of typical deposits and mainly occurs in yinmin formation of kunyang group of middle proterozoic epoch . this paper mainly reports the results of investigation on the ree geochemistry of various rocks and minerals , the sources of ore - forming materials and the age of mineralization . the preliminary mechanism of sudden ree enrichment and mineralization in middle proterozoic has been interpreted
本论文选择迤纳厂矿床为主要研究对象，系统研究矿床不同类型岩(矿)石和矿物的稀土元素地球化学特征，探讨富稀土的成矿流体、成矿物质来源和稀土元素成矿时代，揭示昆阳裂谷初期因民组稀土元素富集的地球化学机制。 - The following new knowledge are acquired : a ) the cu background of stratum and jinningian alkali basite is abnormal high , which could be liberated from those rocks during alteration . cu et al . minerogenetic elements , which main came from magmatic rock , some from stratum ( yinmin formation and luoxue formation ) and its basement rocks
矿床中cu等成矿物质来源复杂，以深源为主，部分来源于地层(因民组紫色层和落雪组白云岩)及基底地层；矿区内的退色蚀变作用可能是混合流体碱质交代改造作用的结果，对铜矿形成影响明显，是铜矿化的标志； 2 - Abstract : according to the composition , the thermal - water sedimentary rocks of yinmin formation in the dongchuang copper ore field can be divided into nine types , of which skarnoid , cupric magnetite carbonate , paracontemporaneous breccia formed in thermal water processing are confirmed and named in this study
文摘:东川铜矿田因民组热水沉积岩根据主要成分可分为9大类，其中类夕卡岩、含铜磁铁碳酸盐岩、热水胶结准同生角砾岩为本次研究确定和命名，其矿物组合、微量元素、稀土元素等地球化学特征表明：它们是海底火山喷流沉积作用的产物。 - 4 ree geochemistry of fluorite , siderite , quartz , magnetite , calcite in ores mainly controlled by ore - forming fluids , in contrasting to those of the metamorphic minerals which controlled by crystal structure . the ore - forming fluids of initial stage show larger lree / hree fractionation than that of later stage . a narrow range of 6 ~ 4s valus for early stage chalcopyrite ( - 0 . 3 to 2 . 8 ) suggested that s originated from the mantle and the 6 13c and 8 18o valus of siderite range from - 11 . 17 to - 15 . 37 % and from 8 ~ 9 . 1 , respectively , it indicates that the c and o of ore - forming fluids were derived from the magma or organogenous sediment
