【摘要】 胶东地区主要金矿类型可分为蚀变岩型和石英脉型2个大类。两者在空间分布上存在着以下关系:矿床具有水平分带,即沿成矿的主构造带以蚀变岩型为主,远离主构造带以石英脉型为主。矿体具有垂直分带,即上有石英脉型金矿,下有蚀变岩型金矿,走向上的分带,即矿体的一段为石英脉型金矿,另一段为蚀变岩型金矿或以复合关系产出。上述认识可用于指导金矿勘查工作。更多还原

【Abstract】 Gold deposits in Jiaodong area can be divided into 2 types as alterted rock type and quartz -vein type. In spacial distribution, these two have the following relations: the ore field has horizontal zoning , namely the alteration rock type is mainly along the main mineralizing fracture belt, while the quartz-vein type is mainly kept away from the main fracture belt. The ore body has vertical zoning , namely there is quartz-vein type gold deposit above, and alteration rock type below. The strike zoning that is had, namely one section of the ore body is quartz-vein type, the other section is alteration rock type or compoundings. Above mentioned understandings can be used in guiding the exploration work of gold deposits.更多还原
