福建尤溪梅仙块状硫化物矿床中的闪锌矿经50％HNO_3浸蚀后发现,微米级的黄铜矿交生体呈乳滴状、棒条状、蠕虫状等沿闪锌矿解理面、双晶面和颗粒边界、裂隙等处分布,并且黄铜矿交生体所占体积均在5％以上,因此闪锌矿中有限的Cu的溶解度使出溶无法解释黄铜矿交生体的成因。交生体的结构特征及其与黄铜矿脉的关系暗示其可能是交代成因。而对横切黄铜矿乳滴的电子探针分析中铁含量特征的研究,证实梅仙矿区闪锌矿中的黄铜矿交生体系含Cu、Fe的热液交代所致。 The sphalerite in the MeiXian massive sulphide deposit in Youxi County, Fujian Province, was found to be eclipsed by 50% HNO3 and found that the micron-sized chalcopyrite was droplet-like in shape, Surface, twin planes and grain boundaries, fissures, etc., and the volume of chalcopyrite is above 5%, so the solubility of limited Cu in sphalerite makes it impossible to explain the dissolution of chalcopyrite Cause. The structural characteristics of the diploid and its relationship with the chalcopyrite veins suggest that it may be the cause of conformation. However, the study on the iron content in the electronic probe analysis of the translucent chalcopyrite droplets confirms that the chalcopyrite intercalation system in the chalcopyrite from Meixian ore district is caused by hydrothermal alteration of Cu and Fe.
