摘　　要：中国泥盆系分布广泛、类型多样,形成于不同的构造古地理背景并蕴藏着丰富的沉积型矿产和化石能源。对中国泥盆纪地层的岩石类型、组合特征及其时空分布特点开展精细解析,有助于我们重建加里东造山运动之后中国主要沉积盆地的形成和演化过程,了解特定区域内地层的基本序列及关键层位空间展布信息,对恢复不同地域的构造、气候环境背景和探寻泥盆系矿产资源的分布特征具有重要意义。本文简要介绍了中国泥盆纪岩石地层的研究历史,依据前人的系统总结和最新的研究成果,重新明确了中国泥盆系地层区划,将中国泥盆系划分为9个地层区和39个地层分区,并以组(或群)为基本单元,结合生物地层和年代地层最新研究进展,提出中国主要地层区72条泥盆纪综合岩石地层剖面的划分和对比方案。The various tectonic and palaeogeographic backgrounds resulted in the development of the complicated Devonian System in China,which is widely distributed and also rich in sedimentary minerals and fossil energy resources.A detailed analysis of the rock types,combination characteristics and spatio-temporal distribution of the Devonian System in China is of great significance for elaborating the dynamics of major sedimentary basins after the Caledonian Orogeny,understanding the lithological sequence and the spatial distribution of key horizons in certain regions,reconstructing the tectonic background and palaeoenvironments,and also exploring the distribution of Devonian mineral resources.In this study,we briefly summarize the research history of Devonian lithostratigraphy of China and redefine the Devonian System regionalization based on earlier and latest researches.Accordingly,9 stratigraphic regions and 39 sub-regions of the Devonian System are recognized in China,and the amended stratigraphic division and correlation of 72 sections involving major stratigraphic regions are also proposed herein in the formation/group level.
