摘　　要：中国石炭纪构造活跃,在华北地块、扬子地块、塔里木地块等稳定块体间存在着大量造山带,尤其存在着北天山洋、南天山洋、布青山—勉略洋、金沙江洋、甘孜—理塘洋等多个洋盆中的洋板块地层,大地构造分区极为复杂。传统的地层区划主要考虑稳定的地块区,按目前的地理格局来进行地层区划划分。本文通过大地构造单元与构造演化阶段相结合,借鉴目前国内经典的大地构造划分方案,对中国石炭纪构造地层进行区划,共划分出阿尔泰—兴蒙地层大区、北准噶尔—西拉木伦地层大区、天山—北山地层大区、塔里木—阿拉善地层大区、华北地层大区、秦祁昆地层大区、扬子地层大区、华夏地层大区、北羌塘—三江地层大区、班公湖—怒江地层大区、印度地层大区等11个地层大区及若干地层区。其中阿尔泰—兴蒙地层大区位置相当于阿尔泰—兴蒙多岛弧盆系,发育洋板块地层及大量岛弧火山岩,分为阿尔泰地层区和兴安地层区;北准噶尔—西拉木伦地层大区位置相当于额尔齐斯—西拉木伦大洋盆,包括大量岛弧带地层及洋板块地层,分为北准噶尔地层区及西拉木伦地层区;天山—北山地层大区位置相当于天山—北山造山系,发育大量火山岩,分为南准噶尔地层区、北天山地层区、南天山地层区、伊犁地层区及额济纳—北山地层区;塔里木—阿拉善地层大区位置相当于塔里木陆块、塔东南—敦煌隆起及阿拉善地块,为稳定的滨浅海沉积,局部为海陆交互相沉积,分为塔里木地层区和阿拉善地层区;华北地层大区位置相当于华北陆块及贺兰山陆缘裂陷盆地,主要为稳定的海陆交互相地层,分为贺兰山地层区、华北地层区及华北地块北缘地层区,其中华北地层区缺乏密西西比亚纪地层;秦祁昆地层大区位置相当于秦祁昆造山系,分为祁连地层区、东昆仑—柴达木地�Frequent tectonic activities occurred in the Carboniferous.Between the stable tectonic units,such as the North China Craton,the Yangtze Craton and the Tarim Craton,there are numerous orogenic belts.Particularly in the fossil oceanic basins,various ocean plate strata are widely distributed,which include the North Tianshan Ocean,the South Tianshan Ocean,the Buqingshan-Mianlue Ocean,the Jinshajiang Ocean and the Ganzi-Litang Ocean.Thus the tectonic subdivision of China is extremely complex.The traditional stratigraphic regionalization mainly refers to the distribution of stable blocks,and the stratigraphic regions are divided according to the recent geographic framework.In this contribution,we reestablished the Carboniferous tectonostratigraphic framework of China.According to tectonic units and evolution stages,and in reference to the Chinese classical tectonic subdivision and by authors’own definition,there are 11 tectonostratigraphic super regions:Altai-Xing’an-Mongolia,North Junggar-Xar Moron,Tianshan-Beishan,Tarim-Alxa,North China,Qinling-Qilian-Kunlun,Yangtze,Cathaysia,North Qiangtang-Sanjiang,Bangonghu-Nujiang and India.Among the tectonostratigraphic super regions,Altai-Xing’an-Mongolia approximately overlaps with the Altai-Xing’an-Mongolia arc-basin system.It contains numerous ocean plate strata and arc-related magmatism and could be divided into the Altai and Xing’an stratigraphic regions.The location of North Junggar-Xar Moron is similar to the Erqis-Xar Moron paleo-oceanic basin.This super region comprises abundant arc-related strata and ocean plate strata,and it could be divided into the North Junggar and Xar Moron stratigraphic regions.Tianshan-Beishan occupies the same territory as the Tianshan-Beishan orogenic system.It possesses several stratigraphic regions,including South Junggar,North Tianshan,South Tianshan,Yili and Ejin-Beishan,and is characterized by considerable volcanic rocks.The location of Tarim-Alxa is equivalent to the Tarim Block,the southeastern Tarim-Dunhuang Uplift and the A
