根据文献资料全面评价表明,黄铁矿Co/Ni比值在矿床成因中是一个比以前所认为的更为可靠的指示剂。这对火山成因黄铁矿矿床尤其是如此,这种矿床的特征Co/Ni比值总是>5,而且通常>10,比沉积的或热液的黄铁矿矿床的更高。而且,有人曾经指出,如果进行合理采样,并把这种地球化学研究扩大到同一地区的许多矿床,那末就可能对该区的成矿历史提 A comprehensive review of the literature shows that the Co / Ni ratio of pyrite is a more reliable indicator of deposit formation than previously thought. This is especially true for volcanic-pyrrhotite deposits characterized by a characteristic Co / Ni ratio of> 5 and usually> 10, which is higher than that of the pyrite deposits deposited or hydrothermal. Moreover, it has been pointed out that if reasonable sampling is taken and the geochemical studies extended to many deposits in the same area, it is possible that the mineralization history of the area
