| 摘 要： | 扬子地台西缘与松潘-甘孜造山带东缘结合部的挖角坝地区,发育了一系列基性岩墙群,对其代表性岩脉的岩相学、矿物学、岩石化学等进行了研究,分析认为基性岩脉可能来源于富集地幔、并在上升过程中有一定量地壳物质的混入.

| Abstract: | Basic rock dyke group in the Wajiaoba region, which lies in the junction position of the western edge of Yangtze platform and the eastern fringe of Songpan-Ganzi orogenic belt, is chosen to study. Petrography, mineralogy and petrochemistry of representative basic rock dykes are discussed. It is concluded that this basic rock dyke group originates from enrichment mantle, and is mixed with some Earth's crust substance during ascending process. |
