【Abstract】 A similarity in geochemical characteristics of rare earth elements exists between veined skarn and granodiorite porphyry, which is related to ore forming process during Late Yanshanian stage in Funiushan copper mine of Nanjing. The study shows that a similar genesis and a variation of geochemical features of rare earth elements present in these two rocks. According to the composition model of rare earth elements and their geochemical features, the formation of veined skarm stems from the further fractional distillation of residual magma.更多还原
