| 摘 要： | 1986—1989年,作者参与了辽宁石炭二叠纪岩相古地理研究专题工作,其间曾赴河南、山西等地考查、学习,积累了中朝板块东部的一些资料,现对研究区石炭纪的沉积特征、古构造、古地理及海侵等有关问题讨论如下(按石炭系三分;由于山西组的时代尚有争论,本文只讨论石炭系本溪组(群)和太原组)。一、区域地质背景本文讨论范围包括吉南、辽东(南)、山东、河北、山西、河南、苏皖及朝鲜半岛北部等中朝板块东部地区。近年来,中朝板块的前寒武纪杂岩中测得超过3400Ma的放射性年龄资料已达14件(王东方,1986),说明其不仅是我国也是全球最古老的地块之一。其上的

| Abstract: | Based on the Carboniferous sedimentary characteristics of eastern Sino-Korean plate, this paper discusses the controls of tectonic movements and palaeogeographic framework on the margin and centre of the basin. Three stages have been distinguished for the uplifting of northern Sino-Korean plate during Carboniferous time. They reflect the onset of uplifting during the late Middle Carboniferous and culmination of uplifting during the early Late Carboniferous, and thus,during the late Late Carboniferous, resulting in the changes in topography higher in the north and lower in the south of eastern Sino-Korean plate. The strong and frequent oscillation movements are considered to be the prevailing tectonic movements during Carboniferous time.
Tte time limit of northern uplifting caused by the plate movements and their controls and influences on the Carboniferous transgression on eastern Sino-Korean plate have been dealt with for the first time. The existence of the Early Carboniferous sediments and transgression on eastern Sino-Korean plate shows that this is a breakthrough in the study of classic stratigraphy, sedimentary facies and palaeogeography. |
