鉴别海相沉积的古地理环境,可以根据一系列成因标志。但是,由于海洋环境微地貌的复杂性(特别是海岸和浅海带),水动力、水化学、生物分布的变化,以及沉积物类型的多样性,大大增加了鉴别工作的困难。很难制定一个一成不变的在任何情况下皆可适合的标准,因此,只有比较深刻地了解了海洋环境中各个带的水化学、水动力和生物界的特征,以及搬运沉积物的流动的基本性质和它们的搬运沉积机理,才可能根据不同的情况进行
Identification of the marine sediment paleogeographic environment, according to a series of genetic markers. However, due to the complexity of the marine micro-topography (especially coastal and shallow kelp), changes in hydrodynamics, hydrochemicals, biodistributions and diversity of sediment types have greatly increased the difficulty of identification. It is difficult to establish an unchanging standard that is suitable under all circumstances and therefore only a more profound understanding of the characteristics of hydraulics, hydrodynamics and the biosphere of each zone in the marine environment and the underlying nature of the movement of sediments And their transport deposition mechanism, it may be based on different circumstances
