| 摘 要： | 重点分析和总结了由显生宙增生复合体和造山带混杂岩重建的年轻造山带洋板块地层--太平洋洋板块地层,也简要介绍了东古印度洋(东新特提斯洋)和古亚洲洋洋板块地层的重建情况。通过对阿拉斯加南部中生代增生地体、俄罗斯远东和中国东北侏罗纪-早白垩世增生复合体、日本二叠纪-侏罗纪-白垩纪等不同时期的增生复合体、菲律宾侏罗纪增生复合体和美国加州海岸山脉中侏罗世-古新世弗朗西斯卡杂岩体等不同单元的岩石学特征、古生物地层学、年代地层学、因逆冲导致的构造叠置和混杂失序特征及演化阶段的分析,重建了太平洋洋板块地层。其中加州海岸山脉中侏罗世-古新世弗朗西斯卡杂岩体的研究比较深入,对该区俯冲带上叠蛇绿岩(大峡谷群弧前盆地蛇绿岩)和弗朗西斯卡北部马林海岬杂岩体(原岩为洋中脊玄武岩)进行了有效区分,不仅还原了太平洋板块的俯冲碰撞过程,还厘清了与之伴生的弧前盆地裂陷和扩张过程。另外,板块俯冲的滞留和幕式增生在活动时间较短的板块俯冲体系中可能不容易识别。

| Abstract: | The paper focuses on reconstruction of the Ocean Plate Stratigraphy (OPS)from young orogenic belts-the Pacific Ocean Plate Stratigraphy,from the Phanerozoic accretionary complex and orogenic mélange,and also briefly introduces reconstruction of the OPS of the eastern ancient Indian Ocean (East New Tethyan Ocean)and ancient Asian Ocean. Through petrology,paleontology and stratigraphy analysis on the Mesozoic accretionary complexes of the southern Alaska,the Jurassic and early Cretaceous accretionary complexes of far east Russian and northeastern China,the Permian-Jurassic-Cretaceous accretionary complexes of Japan,the Jurassic accretionary complexes in the Philippines and the middle Jurassic-Paleocene Francesca accretionary complexes in California,the Pacific Ocean plate stratigraphy are reconstructed. The middle Jurassic-Paleocene Francesca complex in the California coastal mountains has been studied in depth. The overlying ophiolite (Grand Valley Group of the forearc basin ophiolite)in the subduction zone is effectively distinguished from the Marin Cape complex (its protolith is the mid-ocean ridge basalt)in the north of Francesca. The subduction and collision of the Pacific plate and the associated rifting and spreading of the front arc basin are also clarified. Nevertheless,the retention and episodic accretion of the plate subduction with a short lifespan may not be easily identified in the subduction system. |
