摘要: 渤海北黄海地区泥炭的形成主要决定于沿海区的水文条件.受海水直接和间接控制的滨海带和海缘带,在泥炭成矿类型(即泥炭赋存的地貌类型)上有重要的差别;由于晚玉木冰期以来海面升降的发展,导致泥炭赋存状况复杂化,由海向陆,大体可分为:大陆架浅海带、滨海-海缘带、古海缘带.

Abstract: In areas of the Bohai sea and the north Yellow sea,usually the peat in seashore-perimarine sea zone formed in bay,lagoon and submerged valley at the seaside with mountain and hill during the Middle-Late Holocene.The altitude was almost between five and ten metres.Peat was buried mostly in the underground about ten metres in the marginal plain.The peat of paleo-perimafine sea zone formed mainly in the flood plain and gully-valley out of paleocoast line during the period of high sea level,the altitude was almost between ten and thirty metres.The peat of shallow-sea zone was mainly basal peat following the ingression after the late W黵m-glaciation.It spreads in depth-48--56m of shallow plain of the Yellow sea of getting shallower and shallower toward the seashore.The distributional law of peat in these areas, which can be compared with that of Japan sea,indicated that the fluctuations of sea level in the two areas have been synchronism since the W黵mglaciation.
