The Yaolinghe and Wudang Groups at the border between Sichuan,Shaanxi,Henan and Hubei,and in the Wudangshan area of Hubei,the Suixian(Dalangshan) Group in the Suixian Yinshan area of Northern Hubei,and in the original upper“Hong'an Group”in the Xiaogan area,southwest of the Dabieshan Mt.and on the north bank of the Yangtze River of the Huanggan area are essentially the same strata.The original“Yaolinghe Group”is a suite of metabasic volcanic rocks,simple in lithology and small in thickness,and should be reduced to a Formation.Under it is a suite of metamorphic rudaceous and crystal acidic volcanic rocks,the Liulin Formation.Under it is a suite of metaclastic sedimentary rocks and volcanic sedimentary rocks,the Tianxingmiao Formation.The Yaolinghe Formation is missing in Eastern and Central Hubei.The Liuling and Tianxingmiao Formations are distributed from east to west.It is suggested that the above three Formations be unitedly named Wudangshan Group.The Wudangshan Group is overlaid by fossiliferous carbonate strata of the Paleozoic and late Sinian age,and no angular unconformity is seen in between.Its base is not seen,and its age is Early Sinian.

川、陕、豫、鄂边境和湖北武当山地区的耀岭河群—武当群,鄂北随州—应山地区的随县群(大狼山群),大别山西南麓孝感和黄冈地区长江北岸的原红安群上部地层实为同一地层。原耀岭河群是一套变基性火山岩,它岩性单一,厚度不大,应废群复组。其下为一套变质(含砾)含晶屑岩屑酸性火山岩,命名为柳林组。再下是一套变质碎屑沉积岩、火山质沉积岩,命名为天星庙组。耀岭河组在鄂东、鄂中缺失;柳林组、天星庙组横贯东西。建议三组统称武当山群。武当山群上覆有含化石的古生界和上震旦统碳酸盐岩地层,其间没有角度不整合界线;之下未见底,时代为早震旦世

Through 1:50 000 regional geological mapping in the Jianping Kazuo district, western Liaoning province, an attempt has been made to perform multiple stratigraphic division and correlation of the Proterozoic Paleozoic strata, i.e. the lithostratigraphic, chronostratigraphic, biostratigraphic, unconformity bounded stratigraphic and sequence stratigraphic division and correlation. Their essential sequences and sedimentary facies and environments have been investigated and studied in detail. The Proterozoic and Paleozoic strata of the region may be divided into ten sequences and incorporated into two supersequences, namely the Jianping supersequence (Proterozoic) and the Kazuo supersequence (Paleozoic). Based upon these studies, the lithostratigraphic framework and chronostratigraphic framework have been established.

通过1∶5万区域地质调查工作,对建平—喀左地区元古宙—古生代地层做了岩石地层、生物地层、不整合界线地层和层序地层的多重划分与对比。进行了基本层序、沉积相和沉积环境的调查研究,将元古宙—古生代地层划分为10个层序,归并为2个超层序,初步建立了岩石地层和年代地层格架。

The unconformity between the Lower Carboniferous Norco Formation and Middle-Upper Devonian Sumzom Formation in Bomi and its adjacent areas such as the Sumzom and Rawu zones is believed to be an important boundary that represents the conversion of the nature of the Late Palaeozoic basins on northern Gondwana in southeastern Xizang. The Sumzom Formation beneath the unconformity is interpreted as stable carbonate platform deposits, while large-scale volcanism and basin disintegration appear above the unconformity...

The unconformity between the Lower Carboniferous Norco Formation and Middle-Upper Devonian Sumzom Formation in Bomi and its adjacent areas such as the Sumzom and Rawu zones is believed to be an important boundary that represents the conversion of the nature of the Late Palaeozoic basins on northern Gondwana in southeastern Xizang. The Sumzom Formation beneath the unconformity is interpreted as stable carbonate platform deposits, while large-scale volcanism and basin disintegration appear above the unconformity where the deepening-upward depositional sequences represented by the Carboniferous Norco and Laigu Formations rested down following the steadily subsidence of the sedimentary basins and relative rising of sea level. The maximum sea level rise during the Late Carboniferous was manifested by the occurrence of the ferruginous slates and turbidites in the upper part of the Laigu Formation. The successive latest Late Carboniferous to Permian deposits represented by the Luobadui Formation recorded a gradually shallowing-upward depositional sequence. The deepening- and shallowing-upward depositional cycle in the basin has disclosed the evolutionary path from a strone one to a weak one of volcanic activity. The angular unconformable contact of the red continental molasse deposits of the Middle Jurassic Mali Formation with the underlying strata shows that a major orogenic event once took place in the study area during the Late Triassic to the Early Jurassic.

西藏波密及邻区松宗、然乌一带,下石炭统诺错组与中上泥盆统松宗组之间的层序不整合界线是藏东南地区冈瓦纳北缘晚古生代盆地性质转变的重要界面。界线之下的松宗组为稳定的碳酸盐岩台地沉积;界线之上,以大规模的火山活动、盆地裂解为标志,伴随着沉积盆地的持续沉陷和相对海平面的上升,沉积了以石炭系诺错组和来姑组为代表的向上变深序列,相对海平面在晚石炭世达到了顶点,以来姑组上部的含铁质板岩和大套的浊积岩为标志。其后,以洛巴堆组为代表的晚石炭世末期—二叠纪的沉积记录,则代表了一个缓慢的向上变浅的沉积层序。在这个向上变深再变浅的沉积盆地演化过程中,火山活动呈现了明显的由强转弱的变化轨迹。中侏罗统马里组陆相红色磨拉石不整合堆积于下伏地层之上,表明本区在晚三叠世—早侏罗世经历了一次规模宏大的褶皱造山事件。
