福建之下古生界包括寒武系及奥陶系,主要出露于西部沿邵武—长汀和三明—龙岩大致呈两个北东向带状展布。本文作者曾论述过福建西部早古生代地层的划分及对比,在此,拟进一步探讨其沉积建造特征及岩相古地理环境,以供同仁参考。从沉积建造分析,福建下古生界总体上属于以泥砂质为主的复理式建造,系一种较为典 The Paleozoic under Fujian include the Cambrian and Ordovician, mainly exposed in the west along the Shaowu - Changting and Sanming - Longyan roughly two northeast strip distribution. The author of the paper discussed the division and contrast of the Early Paleozoic strata in the western Fujian Province. Here, we intend to further explore the sedimentary construction characteristics and lithofacies palaeogeographic environment for colleagues’ reference. From the analysis of sedimentary structures, the Lower Paleozoic in Fujian generally belongs to the complex type of building with silt mainly,
