摘要：

中国南方是指西至金沙江—元江断裂、西北至龙门山断裂、北至城口—房县—襄樊—广济断裂、东北至郯庐断裂、东至黄海和东海、南至南海的我国南方广大地区。在各露头剖面和钻井剖面地层学和岩石学研究所取得的各种定量及定性资料的基础上，采用单因素分析综合作用法，编制出了中国南方下寒武统下部和中部、下寒武统上部、中寒武统和上寒武统的各种单因素图以及相应的早寒武世早期和中期、早寒武世晚期、中寒武世和晚寒武世岩相古地理图。这些古地理图的最主要特征是定量，即每个古地理单元的划分和确定都有确切的定量的单因素图为依据。这种定量的岩相古地理图在中国南方寒武纪还是首次出现。中国南方寒武纪有7个主要的古地理单元，即滇西台地、康滇陆、扬子台地、斜坡、江南盆地、东南台地和华夏陆。滇西台地、康滇陆、扬子台地、斜坡和江南盆地属康滇古地理体系，东南台地和华夏陆属华夏古地理体系。这两个古地理体系拼合在一起，就构成了中国南方寒武纪的两陆、三台、一盆和一坡和古地理的基本格局。是寒武世早期和中期的岩相古地理特征与早寒武世晚期、中寒武世和晚寒武世岩相古地理特征有明显的不同。这是两个大不相同的演化阶段。这种定量的岩相古地理图在古地理学中是个重大的进展，对石油、天然气以及其他各种矿产的预测和勘探有重要的指导作用。

Abstract:

The south China in this paper refers to the broad region bounded on the west by Jinshajiang River-Yuanjing River Fracture, on the northwest by Longmenshan Fracture, on the north by Chengkou-Fangxian-Xiangfan-Guangji Fracture, on the northeast by Tancheng-Lujiang Fracture, on the east by Huanghai Sea and Donghai Sea, and on the south by Nanhai Sea. The area is about 2 000 000 km2. Based on the quantitative and qualitative data from the study of stratigraphy and petrology of outcrop and well sections, according to the single factor analysis and comprehensive mapping method, the single factor maps of the lower and middle part of the Lower Cambrian, the upper part of the Lower Cambrian, the Middle Cambrian and the Upper Cambrian, and the lithofacies palaeogeography maps of the Early and Middle Age of the Early Cambrian, the Late Age of the Early Cambrian, the Middle Cambrian and the Late Cambrian in South China were compiled. The most important character of these lithofacies palaeogeography maps is quantification. Quantification means that the determination of each palaogeography unit is based on the accurate quantitative data and single factor map. It is the first time in the study of the Cambrian in South China. There are 7 principal palaeogeographic units in the Cambrian in South China, i.e. Dianxi Platform, Kangdian Land, Yangtze Platform, Slope, Jiangnan Basin, Southeast Platform and Cathyasian Land. The Dianxi Platform, Kangdian Land, Yangtze Platfrom, Slope and Jiangnan Basin belong to the Kangdian palaeogeography system. The Southeast Platform and Cathaysian Land belong to the Cathaysian palaeogeography system. These two palaeogeography systems combine together and form the fundamental framework of lithofacies palaeogeography of the Cambrian in South China, i.e. 2 lands, 3 platforms, 1 basin and 1 slope. The characteristics of lithofacies palaeogeography of the Early and Middle Age of the Early Cambrian are different from that of the Late Age of Early Cambrian, Middle Cambrian and Late Cambrian. These are two evolutionary stages of lithofacies palaeogeography of the Cambrian in South China. These quantitative lithofacies palaeogeography maps are an important development in palaeogeography, and are the guide to the prediction and exploration of oil, gas and other mineral resources.
