摘　　要：秘鲁辉钼矿化岩石样品,编号分别为X-1、X-3两件样品先后进行了手标本描述、光学显微镜观察、扫描电子显微镜BSE观察、能谱(EDS)测试和多元素分析测试。含钼岩石样品主要为蚀变黑云母花岗闪长岩,其中暗色矿物主要为角闪石、黑云母,发生强烈蚀变,同时有大量磁铁矿析出。可见辉钼矿交代黑云母或角闪石现象,可能属于钼矿化似斑状花岗闪长岩斑岩体。Peru molybdenite mineralized rock samples are numbered X-1and X-3two samples,hand specimen description,optical microscope observation,scanning electron microscope BSE observation,energy spectrum(EDS)test and multi-element analysis.Molybdenum bearing rock samples are mainly altered biotite granodiorites,of which dark minerals are mainly amphibole and biotite,which are strongly altered,and a large number of magnetite precipitates.The molybdenite metasomatic biotite or hornblende,may belong to the molybdenum mineralization of porphyritic granodiorite porphyry.
