河北省涞源县于城铁矿成因分析

于城铁矿位于中朝准地台山西断隆与燕山台褶带接合部位的军都山构造岩浆岩带涞源杂岩体司格庄岩体中段,本区磁铁矿矿床,产于岩浆岩与白云岩的接触带附近,矿体成群围绕接触带分布,属典型的交代型（或矽卡岩型）磁铁矿矿床,因此,成矿母岩、围岩性质、构造条件等便成了该矿床主要控矿因素。     

海底矿产，来自深海的瑰宝

按美国的青少年俚语说法，如果麦当娜和詹妮弗．洛佩兹成为巨星，并不是因为她们有着庞大的体格，而是因为她们的知名度。同样，海底地质学认为，硫化物矿床之所以受人关注，也并是因为其体积的巨大，而是因为其有着不定型和丰富的金属资源。碰巧的是，海底块状硫化物也有着巨大的体积。虽然由于金融危机导致了人们对矿石的关注度有所下降，但大多数人预计矿石的价格依然会反弹。

Molybdenum isotopic composition as a tracer for low-medium temperature hydrothermal ore-forming systems: A case study on the Dajiangping pyrite deposit,western Guangdong Province,China

Little is known about the range or controls on the molybdenum isotopic composition of low-medium temperature hydrothermal ore-forming systems. We present molybdenum isotope data from 12 hydrothermal syndepositional silicalite and carbonaceous slate samples from the Dajiangping pyrite deposit in western Guangdong Province, South China. The δ ^97/95 Mo values from Orebody III range from −0.02‰ to 0.29‰, with an average of 0.18‰. In contrast, the composition values from Orebody IV display a larger variation from −0.70‰ to 0.62‰. However, the five samples from the main ore bed all show strong negative values. This indicates that the significant variation in molybdenum isotopic composition supports different hydrothermal ore-forming metallogenesis and a metallogenic environment between the two orebodies. Orebody III is likely to have been deposited from submarine exhalative hydrothermal fluids under a relatively strong reducing environment and Orebody IV may have also been influenced by hydrothermal superimposition in a more oxidized disequilibrium condition. In addition, the δ ^97/95 Mo values of Orebody IV are clearly negative, together with the values increasing stratigraphically upward in the ore beds, suggesting that the metallogenic environment of Orebody IV is different from the open oceanic systems. There might be dynamic fractionation in this restricted environment. Therefore, the molybdenum isotope can be used as an effective tracer for the ore-forming fluid and metallogenic environment.
