摘要
奥陶纪是我国地史上最大的海侵时期。奥陶纪地层在我国分布广泛、化石丰富,岩相、生物相分异明显。不同地区岩相、生物相特征既受一定构造运动、古地理位置制约,又是说明和再造当时构造运动和古地理环境的主要依据之一。本文试用活动论的观点探讨中国奥陶纪古地理格局及其沉积环境与生物相特征,以便阐明它们之间的相互关系。
Based on the distribution of ophiolite belts, palaeomagnetic data and analysis of sedimentary environment and biofacies,it is suggested that China in the Ordovician Period was composed of the Sino-Korean,Tarim,South China and part of the Hainan-Indo-China as well as the continental marginal domains of other adjacent plates.They were separated from each other by ocean crusts (Text-fig.1). 1.The Sino-Korean plate was placed in the low latitude tropical region within 30°N latitude
