简介:根据地质并且geochemical学习包括体积岩石的化学分析,稀土元素并且痕量元素研究,液包体,和S和Oisotopic分析,作者详细描述了存款的地质的背景并且为Shaxi斑岩铜黄金存款的形成的条件介绍了重要证明。与在中国和邻近的Cu-Au的另外的大、晚饭大的斑岩铜矿床相比,使矿物化的区域,形成矿石的过程和条件被分析;并且在Shaxi区域形成大斑岩铜矿床的可能性被讨论。现在的学习显示形成矿石的液体和材料主要具有magmatic起源,当天落水在形成矿石的过程起了某个作用时。自从侏罗记,在潜水艇ducting和制服的盘子之间的相互作用在华东为火成岩和金属元素的免职的形成提供了一个主要驱动力。基于Shaxiintrusive的geochemical数据,铜(黄金)矿化作用是,这被发现仔细与在Shaxi区域恼人的象adakite一样的开始有关。这象adakite一样intrusive向华东大陆由于西方太平洋板的俯冲在俯冲环境被形成,在有形成一张大斑岩铜矿床的一个大潜力的地方。
