摘要
黑龙江双鸭山地区早寒武世含金属碱长花岗岩,分布于宝山区东北部。对该地区早寒武世含金属碱长花岗岩的岩石特征进行研究,该岗岩多呈浅肉红色、肉红色,中细粒花岗结构块状构造,该花岗岩属亚含金属碱性—钙含金属碱性岩系,该花岗岩具有轻稀土富集,中等铕亏损的特征。微量元素为Rb、Th、Ti的元素相对富集,而Ba、Sr、Y元素相对亏损,该花岗岩应为在同碰撞期形成的岩浆型花岗岩。
The Early Cambrian, Shuangyashan Heilongjiang area, with the alkali feldspar granite, is distributed in the northeast of Baoshan District. On the region early Cambrian containing alkali feldspar granite rocks characteristics were studied. The granite is shallow red meat, red meat, in fine granite structure massive structure. The granite belongs to sub containing alkali metal calcium containing metal alkaline series of rocks and the granite with a light REE enrichment and middle EU depletion characteristics. The trace elements of Rb, Th, Ti and Ba, the relative enrichment of elements, Sr, Y elements are relatively depleted, the granite should be in magmatic granite formation with collision period.
