摘要 中国古大陆形成及古生代演化是当代地球科学研究的热点之一。经地质学家们多年研究,结合近年来大陆钻探和各大盆地深层油气勘探取得的新进展,认为中国古大陆形成经历了陆核形成、陆核增生及陆块(地块)形成等3个阶段。自南华纪以来的演化经历了4大阶段:①南华纪—中奥陶世的裂陷—克拉通盆地演化阶段;②晚奥陶世—中志留世的俯冲消减挤压克拉通盆地演化阶段;③晚志留世—泥盆纪的碰撞造山挤压克拉通及前渊盆地演化阶段;④石炭纪—二叠纪的拉张—挤压克拉通盆地演化阶段。上述古生代4大演化阶段为中国古生界大油气田(藏)的形成提供了优越的地质条件。 The formation of China's paleocontinent and its Paleozoic tectonic evolution have aroused general interest among Chinese contemporary geoscientists. Based on an overview of many years' research achievements by domestic geologists and the new progress made in recent years in drilling and exploration all over the main land,especially from deep formations in all kinds of basins,it is thought that a. China's paleocontinent has come into being after three main stages:the shape-taking of continental nuclear area,the accretion of remaining continental nuclei,and the formation of continental block,and b. the tectonic evolution of the Cratonic basins had experienced five periods since the Nanhua period:①the continental rift period (Early Neoproterozoic Era);②the ocean basin spreading period (Early Sinian -Middle Ordovician);③the subduction period (Late Ordovician -Middle Silurian);④the collisional orogeny and China paleocontinental union period (Late Silurian -Devonian);⑤the extension-compression-orogenic cycle period ( Early Carboniferous -Early Permian -Late Middle Triassic). Those above-mentioned five Paleozoic tectonic evolution periods provide sound geological conditions for giant Paleozoic oil and gas reservoirs (fields) in China.
