| 摘 要： | 辽东半岛枕状熔岩位于辽河群大石桥组底部的变质基性岩中。呈椭球状个体,具白色硅铝质外壳。岩枕分带明显,由外向内可分为枕壳、冷凝边、枕内相。枕状熔岩的岩石学、岩石化学和地球化学研究表明,它是海底玄武岩的产物。枕状熔岩的发现为揭示广泛发育于辽东半岛早元古宙变质基性岩的成因提供了证据。

| Abstract: | The pillow lava in Liaodong Peninsula occured in the metamorphic-basic rocks oflower Dashiqiao Formation,Liaohe Group,which is ellipsoidal with outer shell of whitesalic.It has obvious zoning,which is divided into pillow shell,condensation rim andinternal facies from outside to inside.The study on petrology,lithochemistry and geo-chemistry of the pillow lava shows that it is the product of submarine basalt.Thediscovery of the pillow lava provides the evidence for the origin of the Early Proterozoicmetamorphic basic rocks in Liaodong Peninsula. |
