| 摘 要： | 西鱼库大型隐伏斑岩钼-钨矿床是近年来在栾川地区开展深部找矿勘查过程中的新发现。该矿床与南泥湖、上房沟钼矿不同,其矿体主要赋存于斑岩体内部而非岩体外接触带的矽卡岩或角岩中。与南泥湖和上房岩体相比,西鱼库隐伏斑岩体的Si O2、K2O含量略低,具有正Eu异常,表明西鱼库隐伏斑岩体比南泥湖和上房岩体分异程度略低,更接近成矿岩浆中心位置。

| Abstract: | Xiyuku large concealed porphyry Mo-W deposit is recently discovered during the process of national deep mineral exploration. The main orebodies are hosted in plutonic porphyries rather than the skarn or the hornfels of the outer contact zone of the related plutons, which are evident characteristics of the Nannihu and Shangfang Mo deposits. Compared with the Nannihu and Shangfang plutons, the Xiyuku pluton owns slightly lower SiO2 and K2O content as well as positive Eu anomalies, suggesting that Xiyuku pluton has lower differentiation degree and may situate closer to the centre of underlying batholith. The inversion of high-precision gravity data and exploration geochemistry data also support that Nannihu, Shangfang and concealed Xiyuku stock are linked together underground while the negative Bouger gravity anomalies and anomalies of high-temperature element Mo and W from stream sediment survey are overlapped. Meanwhile, the existing large Mo-W mineral deposits are all in the overlaying anolmolies area. It is just the underlying batholith which provides the metallogenic material and the energy for the mineralization. This means that there is enormous potentiality for finding concealed porphyry Mo-W deposits in the area, especially around Xiyuku area. |
