一、前言 任何地质作用过程都是复杂的,东海也不例外,其沉积过程具有长期性、继承性和叠加性的特点。因而反映在矿物组合及其分布变化上较为复杂,影响因素颇多。然而,运用数学地质方法却可帮助我们寻找和确定其主要的影响因素,查明它们的相互关系,甚至建立定量描述的模式。而这正是传统地质学研究中的难题之一。 关于东海沉积物矿物学问题,近年来我们做了一些工作,并取得了初步的认识。在此基础上,本文试用数学地质方法,定量地研究东海陆架区现代、混合,残留三种环境沉积 I. Preface Any geological processes are complex, the East China Sea is no exception, the deposition process has the characteristics of long-term, inheritance and superposition. Therefore, it is more complicated to reflect changes in mineral assemblages and their distribution, and there are many influencing factors. However, the use of mathematical geologic methods can help us find and identify its main influencing factors, identify their interrelationships, and even establish a quantitative description of the model. This is exactly one of the problems in the study of traditional geology. With regard to the mineralogy of the sediments in the East China Sea, we have done some work in recent years and made preliminary understandings. On this basis, this paper attempts to use mathematical geology methods to quantitatively study the three kinds of environmental sediments in the East China Sea shelf area: modern, mixed and residual
