| 摘 要： | 黄铁矿是一种分布广泛的硫化物,但不同条件下形成的黄铁矿中微量元素的分配各具特点。本文通过对黄铁矿空间分布特征及其中多种微量元素分配特点的研究,提出黄铁矿晕的概念,讨论了其地质意义,对南北两矿带成因的同一性提供了新的信息,并提出矿体不同部位黄铁矿中Co/Ni比值的差异规律可作为判断矿体剥蚀深度的标志。

| Abstract: | The space distribution of pyrite and the concentrations of some trace elements (Cu, Zn, Pb, Co, Ni, Mn, Ti)as well as the Co/Ni ratio are described in this paper.Based on the data obtained, a pyrite halo is confirmed and its geological significance explained, some new evidences on the consistency in origin of the two ore zones studied have been revealed. The systematic change in Co/Ni may serve as a criteria by which the erosion level of a given orebody may be inferred. |
