| 中文摘要: |
| 阐述了安林地区任村—岳城一带早白垩世岩浆岩分布、岩性特征。从岩石学、地球化学等多个领域对测区早白垩世岩浆活动作了深入的研究,探讨了岩浆岩的成因类型、构造环境。提出测区岩浆岩具Ⅰ型花岗岩特点,成岩物质来源于壳幔质重熔岩浆,属于与陆内俯冲有关的钙碱性—碱性花岗岩的新认识。探讨了区内岩浆岩的成矿专属性,为铁矿的成矿预测奠定了基础。 |
| 英文摘要: |
| The distribution and lithologic combination of early Cretaceous magmatic rocks in Anlin area were expounded. In this paper, the early Cretaceous magmatic activities in the measurement area are studied in terms of petrology, geochemistry, etc. It is proposed that magmatic rocks in the measurement area have the characteristics of type I granite. The diagenetic material is derived from the mantle mass and is mainly remelted magma. It belongs to the new understanding of calcium-alkaline granite related to land subduction. This paper discusses the specific characteristics of magmatic rocks in the area and lays a foundation for the ore metallogenic prediction. |
