摘要
广西都庞岭地区南竹河锡多金属矿床矿脉在平面上的分布规律具有"线性递变不等距"规律。矿脉矿石品位在平面上具有"中富侧贫",在垂向上具有"上富下贫"的特征。矿脉的矿化在平面上的分带性为"北部富锡,南部富钨"。矿床垂直构造分带性为"三层楼"分带模式。NNE向断裂和NW-NNW向断裂联合控矿是区内最重要的控矿规律。成矿分为两期:燕山早期形成NNE向矿脉,是矿区的主要成矿期;燕山中期形成NW-NNW向矿脉,是次要成矿期。
The distribution of mineral veins of the Nanzhuhe tin-polymetallic ore deposit in the Dupangling district of Guangxi is characterized by ＂a linear variation pattern＂ horizontally.The ore grades of the veins are characterized by ＂rich in the center and hungry at the sides＂ horizontally and ＂rich upward and hungry downward＂ vertically.The mineralization of veins displays a pattern of ＂rich in tin at the north and rich in tungsten at the south＂ horizontally.The structure of the deposit is a ＂three-storied＂ zoning model vertically.Mineralization is structurally controlled by NNE and NW-NNW fractures,which is the most important ore-control pattern.The mineralization can be divided into two stages,that is,the major mineralization of NNE veins at the early Yanshan period and the minor mineralization of NW-NNW veins at the middle Yanshan period.
