PETROGENESIS AND TECTONIC SIGNIFICANCE OF GRANITE IN THE HAOYAOERHUDONG GOLD DEPOSIT IN INNER MONGOLIA

  • 摘要: 内蒙古浩尧尔忽洞金矿为低品位超大型中低温热液型金矿,矿区内海西期花岗岩发育。在矿区内可见黑云花岗岩、花岗细晶岩、花岗伟晶岩和花岗斑岩。花岗岩中SiO2含量65.36%~74.29%,Na2O/K2O比值0.43~1.01,平均值为0.75,花岗脉岩类属于高钾钙碱性,黑云花岗岩属于钾玄岩系列。哈克图解上各元素含量随SiO2变化呈线性规律明显,具Ⅰ型花岗岩特征。∑REE值在64.86×10-6~164.80×10-6范围内变化,总体上稀土含量较低。(La/Yb)N值为6.59~16.98,显示轻重稀土有明显的分馏。稀土元素蛛网图表现为右倾。黑云母花岗岩δEu平均值0.30,具低Sr低Y的特点。花岗脉岩类δEu平均值为0.65,表现出高Sr低Y的特点。花岗岩类具有中等到强的铕亏损。根据其地球化学特征,认为该岩体为同碰撞—后碰撞期形成的高钾钙碱性Ⅰ型花岗岩。
