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 6 、昆陽群因民組地層中出現的稀土富集、成礦與我國的白云鄂博稀土ree一fe一nb超大型礦一床和澳大利亞的olympicdamcu一u一au一ag一ree超大型礦一床，在成礦時代、產出大地構造背景、成礦物質來源等方面具有較大的相似性，均體現成礦受控于中元古代1 |
