Abstract

The ore–metasomatic zoning of the Svoboda locality, which is one of the centers of mineralization on the Malmyzh Au–Cu porphyry deposit, is reported. The central part of the ore bodies is composed of quartz–sericite and biotite–feldspar metasomatic rocks that bear relatively rich Au–Cu mineralization. The flank zones of ore bodies are mostly composed of phyllisite and propylite. These zones are characterized by high concentrations of Pb, Mn, and Zn. A positive correlation was detected for two groups of elements: Mo–Cu–Au and Pb–Zn–Mn. Based on analysis of the vertical change in the contents of ore components and their relationships, the modern erosion level at the upper part of the ore body has been proposed.

Malmyzh Au-Cu斑岩矿床Svoboda地区的矿石-物相带分区

摘要

据报道，Svoboda地区的矿石-物变区带是Malmyzh Au-Cu斑岩矿床的成矿中心之一。矿体的中心部分由石英-绢云母和黑云母-长石交代岩石组成，它们具有相对丰富的金铜矿化作用。矿体的侧翼带主要由辉绿铁矿和丙铁矿组成。这些区域的特征是高浓度的Pb，Mn和Zn。两组元素之间存在正相关：Mo–Cu–Au和Pb–Zn–Mn。在分析矿石成分含量及其关系的垂直变化的基础上，提出了矿体上部的现代侵蚀水平。
