| 摘 要： | 辽西地区长城纪常州沟期—团山子期由陆源碎屑岩沉积底垫始,至形成稳定的碳酸盐岩台地止,构成了一个完整的海侵—海退旋回.根据其岩石组合、沉积构造、指相微量元素、古盐度及稀土元素比值等测试成果分析,这一时期沉积相做有规律的变化,早期发育河控三角洲相,中期发育无障壁海岸相、浅海陆棚相,晚期为有障壁海岸相、开阔台地相、局限台地相.

| Abstract: | The deposition during Changzhougou Age to Tuanshanzi Age of Changcheng Period, started from the terrigenous clastic rock foot-plate and ended by the stable carbonate rock platform, forms a complete transgression-regression cycle in Western Liaoning Province. Based on the analysis of rock assemblage, sedimentary structure, index trace elements,paleosalinity and rare earth element ratio, a regular change of sedimentary facies is found. The river delta facies is developed in the early stage; the non-barrier coast facies and shallow sea shelf facies in the middle stage; while the barrier coast facies,open platform facies and restricted platform facies, the late stage. |
