自然界有些事物,尽管它们的成因各异,然而在形态和外貌上却极其相似。犹如冰碛物、坡积物、坍塌堆积物等之类似于泥石流堆积物一样。详细研究它们的沉积物特征,并从沉积相——环境的角度,解释这些特征,从而建立各个沉积物各自的、独特的沉积特征,并用以鉴定、区分它们,是陆相沉积研究中的一个重要任务。 Some things in nature, although they have different causes, are very similar in morphology and appearance. Like a moraine, slope sediments, collapsed sediments and the like similar debris flow debris. A detailed study of their sediment characteristics and interpretation of these characteristics from sedimentary facies-environment point of view, in order to establish their own unique sedimentary characteristics of each sediment, and to identify, distinguish them, is one of the continental deposition studies Important task.
