在大陆裂谷的沉积模式研究中有两种主要论点,它们分别把气候和构造视为大陆裂谷系发展过程中控制沉积相展布的唯一首要因素.在古裂谷环境中,构造史的细节及其与具体沉积特征间的关系常无法确定.然而,在现代裂谷中却能观察到对类似于古裂谷中的沉积起控制作用的构造.水文将讨论现代裂谷盆地内各别构造单元与沉积作用之间的特定关系,并力图证明这些关系存在于种种不同气候背景中,在确定裂谷充填地层的性质时十分重要.所以,笔者认为首先必须建立一种能适用于大多数大陆裂谷背景的构造模型,以提供后文讨论的基础.
There are two main arguments in the study of sedimentary patterns in the continental rifts that consider climate and tectonics, respectively, as the only primary factor controlling the distribution of sedimentary facies during the development of the continental rift system.In the ancient rift environment, The details and their relationship to specific sedimentary features are often undetermined, however, structures that are similar to the controls in the Palaeozoic can be observed in the modern rift Hydrology The various tectonic units in the modern rift basins And sedimentation and try to prove that these relationships exist in different climate backgrounds and are very important in determining the nature of the rift-filling formation.Therefore, I believe that we must first establish a suitable for most of the continental crack The tectonic model of the valley background provides the basis for the discussion that follows.
