LITHOFACIES PALEOGEOGRAPHY OF NANHUA PERIOD IN LIAONING REGION

摘要: 辽宁南华纪地层主要分布于辽东半岛，零星见于辽北铁岭地区.南华纪沉积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.通过对南华纪岩相古地理特征的较深入研究，根据其岩性组合、沉积构造、指相化石等特征划分出6个沉积相，即滨岸相、浅海陆棚相、开阔台地相、局限台地相和河流-冲积扇相.Abstract: The strata of Nanhua Period are mainly distributed in the Liaodong Peninsula and scattered in Tieling area in Northern Liaoning Province. The Nanhau sedimentary period, which started with terrigenous clastic rocks as bottom, until the forming of stable carbonate rock platform, composed a complete progression-regression cycle. With study on the lithofacies paleogeographic characteristics of the Nanhua Period, according to its lithologic assemblage, sedimentary structure and facies fossils, six sedimentary facies are assigned, i.e. littoral facies, neritic shelf facies, open platform facies, restricted platform facies, fluvial facies and alluvial fan facies.
