Formation mechanism of the Huangjindong gold deposit, Northeastern Hunan ore cluster: Constraints from trace elements compositions of arsenopyrite and pyrite
-
摘要:
研究目的 湘东北矿集区黄金洞金矿是江南古陆典型的大型金矿床，探明金资源量约80 t，平均品位5 g/t，矿体主要赋存于新元古代冷家溪群板岩中。通过研究黄金洞金矿中载金硫化物的微量元素组成及其不可见金的赋存状态，揭示巨量金的富集过程。
研究方法 本次研究对黄金洞矿区开展了详细的野外地质考察，对金成矿阶段的主要载金矿物毒砂和黄铁矿进行了系统的显微结构、激光剥蚀等离子质谱仪（LA−ICP−MS）微量元素分析。
研究结果 电子探针显微结构研究结果表明，黄铁矿和毒砂在背散射图像中主要呈均一结构，环带结构不明显。LA−ICP−MS微量元素分析结果显示，黄铁矿中不可见Au含量为3.1×10−6~111.5×10−6，平均为31.9 ×10−6；毒砂中不可见Au含量为0.6×10−6~279.4×10−6，平均为67.2 ×10−6。黄铁矿中的不可见金含量均分布在饱和线下方，暗示这些不可见金主要为晶格金。系统的剥蚀信号图分析发现，少数分析点位中不可见金的信号出现“尖峰”，暗示存在微米尺度的纳米金颗粒。研究收集了江南古陆已发表的燕山期典型大型金矿床中黄铁矿和毒砂微量元素数据，发现Sb、Cu、Se、Te等元素含量在不同元素组合矿床中存在一定差异，表明载金硫化物的微量元素组成可在一定程度上揭示区域成矿差异。
Abstract:Objective The large−scale Huangjindong gold deposit is one representative gold deposit in the Northeastern Hunan ore cluster, Jiangnan terrain, and it has gold resources about 80 tons, and the average grade is about 5 g/t. The orebodies mainly occur in the slates of the Neoproterozoic Lengjiaxi Group.
Methods In order to reveal the processes of large−scale gold enrichment, the trace element composition of gold−bearing sulfides and the occurrence mechanisms of invisible gold in the Huangjindong gold deposit are researched in this study. Detailed field geological investigation, texture revealed by electron probe microstructure and trace elements determined by laser denudation plasma mass spectrometer (LA−ICP−MS) were carried out in this work. The results show that pyrite and arsenopyrite have homogeneous texture, and the zone texture is lacking. LA−ICP−MS trace element analyses result show that the invisible Au content in pyrite ranges from 3.1×10−6 to 111.5×10−6, with an average of 31.9×10−6. The invisible Au content in arsenopyrite ranges from 0.6×10−6 to 279.4×10−6, with an average of 67.2×10−6. The invisible gold content in pyrite lies below the saturation line, suggesting that the invisible gold is mainly lattice gold. There are a few gold nanoparticles revealed by the peak signals. By comparing the published trace element data of pyrite and arsenopyrite from the Yanshanian large gold deposits from the Jiangnan terrain, we discover that contents of Sb, Cu, Se and Te are of certain differences among these deposits with different elemental assemblage, indicating that, to some extent, trace element composition of gold−bearing sulfide could provide important information on the ore−forming processes differences.
