| 摘 要： | 结构单元分析就是结合古流数据对露头横剖面进行岩石相、界面和结构单元的划分，以揭示沉积体系的三维展布，恢复沉积体系的演化史，它是目前研究露头沉积地质的最佳方法之一。本文对结构单元分析法的原理及其在几类沉积体系中的应用作了介绍。在此基础之上，讨论了结构单元分析法存在的几个问题以及它与层序地层学的关系。

| Abstract: | The architecture element analysis is to plot out the lithofacies, bounding surfaces and architecture elements connected to palaeocurrent data on the photomosaic profiles of outcrops in order to illustrate the three - dimensional distribution of depositional systems and reconstruct their de-positional history. It is one of the best methods to study sedimentary geology for outcrops. A review of the principle of architecture element analysis and its applications to several types of depositional systems is given in this paper. Based on these, several problems with this method and its relationship with sequence stratigraphy are discussed. |
