紫金山金铜矿二元铜硫化物成分特点的初步研究
Preliminary compositional investigation of binary Cu sulfidesfrom Zijinshan Au-Cu deposit
摘要
Abstract
In this paper, the chemical composition of some binary Cu sulfides from highly sulfidized epithermal Zijin-shan Au-Cu deposit was investigated, and mineral phases in the ores were determined with electron microprobe analysis, X-ray diffraction and vibrational spectroscopy. Djurleite (Cu1.97S)and yarrowite(Cu1.25S)from this ore deposit were recognized for the first time. In addition to the replacement of digenite (Cu1.80S) by covellite (Cu1.01S), some covellite was replaced by digenite and anilite (C111.75S). These phenomena imply that these Cu sulfides were formed contemporarily from the same hydrothermal solution, but under different oxidization-deoxi-dization conditions. The formation of these minerals resulted from the alteration of the earlier primary sulfides by Cu-rich hydrothermal solutions.关键词
