成岩作用是沉积物转化为变质岩之前的一系列重要作用的总合,成岩作用的性质和强度控制了岩石的总特征,因而研究成岩作用具有重要的理论和实际意义。关于成岩作用的定义和成岩阶段的划分等问题,多年来存在着很大的分歧。综合国内外常见术语和划分方案可将成岩作用划分为同生和准同生作用、成岩作用、后生作用和表生作用等五个阶段。通过岩石的组构类型和某些颗粒的结构特征及变化研究成岩作用,不失为一种常用而有效的方法。
Diagenesis is the sum of a series of important functions before the sediments are transformed into metamorphic rocks. The nature and intensity of diagenesis control the general characteristics of the rocks. Therefore, studying diagenesis has important theoretical and practical significance. There are many disagreements over the years about the definition of diagenesis and the division of diagenetic stages. The diagenesis can be divided into five stages of syngenetic and quasi-syngenetic, diagenetic, epigenetic and epigenetic effects by synthesizing common terminology and division programs both at home and abroad. It is a common and effective method to study diagenesis through the structural types of rocks and the structural features and changes of some particles.
