在海洋地质学中,分类问题是广泛存在的。譬如,古生物的种属;岩石、矿物的类别;地层的划分;构造的区划等等。其中,海洋沉积物的分类是经常遇到的一种分类问题。由于沉积物的类别能在一定程度上反映出沉积物的成因和环境特征,这对于海洋沉积学或海洋工程学都具有十分明显的意义。 以往,沉积物通常是以粒度大小来进行分类的。就沉积物的这一特征(一种参量)而言,是可以确定一个固定的界限作为划分不同沉积物类别的定量标准的。但是,当我们采用矿物组份或地球化学特征来对沉积物进行分类或组合时,由于每一特征都具有多种参量,这
In marine geology, the classification problem is widespread. For example, the species of paleontology; rock, mineral types; stratigraphic division; structural division and so on. Among them, the classification of marine sediments is often encountered as a classification problem. Because sediment types can reflect the genesis and environmental characteristics of sediments to a certain extent, this is very significant for marine sedimentology or marine engineering. In the past, sediments were usually classified by size. For this feature of sediment (a parameter), a fixed limit can be established as a quantitative criterion for the classification of different sediment classes. However, when we classify or combine sediments using mineralogical or geochemical features, since each feature has multiple parameters, this
