本文用化学物相分析研究了喀拉通克铜镍硫化物矿床中伴生贵金属Au、Ag、Pt、Pd的赋存状态.国内外尚未见报导.得出了与前人不同的认识,各成矿作用下形成的矿体,贵金属赋存特征有差异,Au、Ag主要赋存于硫化物中,其次为自然金银及其互化物,热液作用下则趋向硫化物中富集.独立的Pt、Pd矿物在Ⅰ、Ⅱ、Ⅳ矿体占优势,块状硫化物和脉石矿物中赋存一定量的Pt、Pd;Pt、Pd在热液成矿作用中有叠加富集趋势;Pt在Ⅰ和Ⅳ矿体最为富集;Pt在Ⅳ中最富集;形成热液叠加成因的Pt、Pd矿体.伴生贵金属元素赋存富集规律研究,为进一步研究其复杂的成矿作用打下了基础.
In this paper, the chemical state analysis of the occurrence of associated precious metals Au, Ag, Pt and Pd in the kalatongk copper-nickel-sulfide deposit has been carried out. No reports have been reported at home and abroad. Different understandings have been obtained from the previous studies. The ore bodies and precious metals formed under the different mineralization have different occurrence characteristics. Au and Ag mainly occur in sulfide, followed by natural Au, Ag and their intermetallics, hydrothermal fluids Under the action tends to sulfide enrichment. The independent Pt and Pd minerals predominate in ore bodies Ⅰ, Ⅱ and Ⅳ, and a certain amount of Pt and Pd exist in massive sulphide and gangue minerals. Pt and Pd have the tendency to superposition and enrichment in hydrothermal mineralization ; Pt is most abundant in the ore bodies of Ⅰ and Ⅳ; Pt is the most abundant in Ⅳ; and Pt and Pd ore bodies are formed by superposition of hydrothermal fluids. The research on the occurrence and enrichment of associated precious metal elements lays the foundation for further study of its complex mineralization.
