| 摘 要： | 华南陆缘中生界地层以广东省出露最广,这套地层为陆源碎屑沉积岩,局部为火山岩。上三叠统—上白垩统划分为2个巨层序、7个超层序和15个层序。沉积充填序列展示出本地区经历了海侵-海退过程,沉积环境由海相转化为陆相环境。3个级别的海平面变化控制了层序、超层序和巨层序的发育。粤中--粤东地区中生界发育的Ⅲ级层序可归纳出3种类型:浅水型、深水型和湖盆型;浅水型层序又可以分为浅水Ⅰ型和浅水Ⅱ型。

| Abstract: | The Mesozoic strata of the continental margin in South China are widely exposed in Guangdong,including continental clastic sedimentary rocks mainly,and volcanic rocks partly.The Upper Triassic-Upper Cretaceous can be divided into 2 mega-sequences,7 supper-sequences and 15 sequences,showing a process of transgression-regression during the sedimentary environment changed from marine to terrestrial.The sea level change of the three grades controlled the development of sequences,supper-sequences and mega-sequences.The Mesozoic Ⅲ-sequence developed in central and eastern Guangdong can be concluded for 3 types,including shallow water,deep water and lacustrine basin types,and the shallow water type can be divided into types Ⅰand Ⅱ,further. |
