| 摘 要： | 从花岗岩的岩石化学、微量元素特征和稀土元素特征分析江西茅坪钨锡矿床花岗岩的地球化学特征,结果表明茅坪钨锡矿床花岗岩富硅、铝、锰,贫钛、铁、镁、钙、磷,属于强铝过饱和S型花岗岩,形成于板内的伸展—拉张环境,属于同碰撞花岗岩。通过黑云母花岗岩和云英岩化花岗岩地球化学特征的对比,黑云母花岗岩可能为茅坪钨锡矿床的形成提供了部分物质来源。

| Abstract: | The geochemical characteristics of Jiangxi Maoping Tungsten-tin Deposit Granite are analyzed in the view of the granite rock chemistry,trace element and REE characteristics.The results show that Maoping Tungsten-tin Deposit Granite riches in silicon,aluminum,manganese;poor titanium,iron,magnesium,calcium,phosphorus which belong to the strong aluminum oversaturated S-type granite.They are formed in an intraplate extension-extension environment and belong to the same collision granite.By the contrast of geochemical characteristics between biotite granite and greisen granite,the biotite granite may provide some of the material sources for Maoping Tungsten-tin Deposits. |
