本文试图从中国斑岩铜(钼)矿的时空分布规律、成矿斑岩的建造特征和矿化特征等几个方面对我国斑岩铜(钼)矿加以分析,并与国外有关资料进行简要对比。一、中国斑岩铜(钼)矿的时空分布规律早中元古代,中条山一带原始优地槽内,在喷发基性和中酸性火山岩系的同时或稍后,有中基性及中酸性次火山岩体侵入,形成斑岩铜(钼)矿萌芽状态的铜矿峪式铜矿。加里东运动后,这种萌芽状态的斑岩铜矿趋于消失。我国西起北天山以北,东至大、小兴安岭、长白山北段属古亚洲地槽区。该区在华力西期(表1),在地背斜隆起上,或古岛弧带,生
This paper attempts to analyze the porphyry copper (molybdenum) ore in China from several aspects, such as the temporal and spatial distribution of porphyry copper (molybdenum) ore in China, the characteristics of the mineralization porphyry and its mineralization characteristics. Compared. First, the Chinese porphyry copper (molybdenum) ore temporal and spatial distribution of the Early Mesozoic, Zhongtiaoshan area of the original gifted tank, eruption basic and acidic volcanic rocks at the same time or later, with the basic and medium Acidic subvolcanic intrusions, the formation of porphyry copper (molybdenum) sprouts of copper mine valley type copper mine. After the Caledonian movement, the budding copper porphyry tended to disappear. From the north of the North Tianshan Mountains in the west to the east and the small Xingan Mountains in the west, the northern section of Changbai Mountain belongs to the ancient Asian terrain area. The area in the Variscan period (Table 1), uplift in the anticlinal, or ancient island arc, students
