| 摘 要： | 本文在海南岛全新世红树林泥炭及其含沉积特特征，形成环境详细研究的基础上，对比会南晚更新世以来的海平面变化，综合分析得出：红树林泥炭形成于泥炭坪相；晚更新世晚期－全新世的快速海侵为含炭沉积的形成提供了古地理背景；红树林泥炭发育于４０００ａ以来的海平面波动上升时期；泥炭坪的发育主要取决于海平面的上升速度和植物有机质的堆积速度。海南岛全新世海侵成碳的研究为华北晚古生代含煤建筑的解释提供了比较沉积学的论据

| Abstract: | Holocene mangrove peat deposits were found in Dongzhaigang of Qiongshan County ,Futian of Qionghai County and other aresa of Hainan Island. The mangrove peat is an exceptional kind of peat formed in tidal-flat environments of tropical and subtropical coast because of its special composition, distribution, associated deposits, peat-bearing depositional sequence, peat-forming environments and evolution. On the basis of the above researches and by contrast with the sea-level changes since Late Pleistocene in South China,the authors,after comprehensive analysis,have drawn the following conclusions: (l)Mangrove peats form on peat flats and high-tidal flats are the best places for peat flat development, (2)Transgression provides paleogeographic setting for the formation of peat-bearing deposits from late Late Pleistocene to Holocene, (3)Mangrove peats develop during sea-level rise periods since 4000a. B. P. , (4)Development of peat flats depends on sea-level rise rate and organic accumulation.
Most Paleozoic coal seams possess the characteristics of broad distribution, stable stratohorizon, association with limestone and so on. Study of transgressive genesis of Holocene peats in Hainan Island gives the evidence of comparative sedimentology for explaining the origin of Late Paleozoic coal-bearing formations in North China. |
