The genetic nlechallism of the shallowinguupward carbonate sequences is that the carbonate prodtlctloll rates are greater than the tectonic subsidence rates, hut smaller than therelative risillg rates of sea- level changes. So the shallowing upward carbonate sequencesare developed On the "drowning unconformity surface,' resulted from the platform drowning evellts. These carbonate sequences are con1Posed of the vertica stacking patterns ofvarlotls nletrc scale cyclic sequences. In the rising stages of low-frequency sea-levelchanges, the metre scale cyclic sequences are characterized by the 'drowning band", whileby the "exIJosillg band,' in the stalldstill and fall stages. The condensed sections consistingof the lower units of the shal lowing-upward sequences become progresslvely t hinner frombasinwards to plat formwards. The limestones in t he Triassic Daye Formation in theGuiyang area comprise two shallowing t]Pward carbonate sequences, each of which, Inturn,consits of various metreuscale cyclic sequences.

碳酸盐向上变浅层序形成的主因乃因在被动大陆边缘至克拉通盆地中,构造沉降速率一般要小于碳酸盐生产速率,而碳酸盐生产速率又要小于海平面变化相对上升速率。由此就形成了台地淹没事件形成的“淹没不整合”界面之上发育的碳酸盐向上变浅层序。这种低频率海平面变化快速上升超过碳酸盐生产速率形成的向上变浅层序,可由许多种类型的米级旋回层序有规律的垂直叠加所构成。在低频率海平面变化的上升阶段则以淹没节拍为主的米级旋回层序为特征,而在停滞至下降阶段则以暴露节拍的米级旋回层序为特征。而且组成向上变浅层序的下部单元──淹没事件形成的凝缩面具有从靠近盆地区到靠近台地区变薄的趋势。贵阳地区三叠系大冶组灰岩由两个向上变浅层序组成,每一层序包括若干个不同类型的米级旋四层序。

Different from the type Ⅰ(LST+TST+CS+HST)and type Ⅱsequences (SMT+TST +CS +HST) which are defined by sequence stratigraphy, the third-order carbonate cyclic sequences of drowned unconformity type is marked by“CS+HST” successions in which a condensed section lies directily the sequence boundary, and the hasal sequence boundary is a drowned unconformity surface or a deepened starved punctuated surface distinguished from the type Ⅰ and type Ⅱ sequence boundary created by the exposure-punctuation events. This type...

Different from the type Ⅰ(LST+TST+CS+HST)and type Ⅱsequences (SMT+TST +CS +HST) which are defined by sequence stratigraphy, the third-order carbonate cyclic sequences of drowned unconformity type is marked by“CS+HST” successions in which a condensed section lies directily the sequence boundary, and the hasal sequence boundary is a drowned unconformity surface or a deepened starved punctuated surface distinguished from the type Ⅰ and type Ⅱ sequence boundary created by the exposure-punctuation events. This type of carbonate cyclic sequences is the products of the condensation processes on the carbonate platforms that is produced by the platform drowning event,and is characterized by a generally asymmetrical upward-shallowing facies sequence.The characteristics of the four Late Cambrian third-order carbonate cyclic sequences of drowned unconformity type in the northern part of North China indicate that the platform drowning events and concomitant condensation are not typical of third-order cyclic sequences,they often occur in the high-frequency sea-level changes. It follows that the condensed sections ought to belong to the cyclic sequences of various orders,which are not only a genetically composite unit of the third-order cyclic sequences.

与层序地层学定义的类型Ⅰ层序(LST+TST+CS+HST)及类型Ⅱ层序(SMT+TST+CS+HST)不同,淹没不整合型碳酸盐三级旋回层序以凝缩段直接覆盖在层序界面之上形成的,“CS+HST”序列为特征,而且其底界面为一淹没不整合面或加深饥饿间断面。该类型三级旋回层序是碳酸盐台地淹没事件产生的凝缩作用过程的产物,它以总体向上变浅的非对称相序为特征。华北北部晚寒武世地层中发育的四个淹没不整合型三级旋回层序的相序特征表明,台地淹没事件及其相关的凝缩作用,只要沉积背景适合,并非三级旋回层序所独有,高频率海平面变化也常产生“瞬时淹没”,因而凝缩段并非都发育在最大海侵期,并且凝缩段也存在级别归属问题。

The paper deals with the sequence stratigraphy on Neoproterozoic (1000-57OMa) outcrops in the area.

The Neoproterozoic successions in northwest Hunan, South China belong to a stable sedimentary re- gion of paleo-continental margin along the southeast border of Yangtze platform. The paper deals with the sequence stratigraphy on Neoproterozoic (1000-57OMa) outcrops in the area. Adopting a dividing plan of gallery-typed section and comprehensive sequence stratigraphy, 14 Ⅲ order sequences are divided from Neoproterozoic successions in the stable shallow marine area, based on careful field investigations on out- crops, i. e. 4 sequences in Laoshanya Formation (equal to Banxi Group); 2 in Dieshuihe Formation (equal to Liantuo Formation); 1 in Dongshanfeng (equal to Jiangkou Formation) - - Xiangmeng Formations ; 1 in Nantuo Formation; 2 in Doushantuo Formation and 4 in Dengying Formation. Altogether 7 type-I se- quence boundaries and 7 type-II sequence boundaries and 1 immersed uncomformity are identified on out- crops. By a orrelation of sequence stratigraphy over the whole area (including Dongkou area in central Hu- nan), a Sinian (800-570Ma ) synchronous stratigraphic framework is established in norhtwest Hunan. It is concluded that a synthetic approach suitable to the Neoproterozoic sequence stratigraphy on outcrops across the area should be adopted. And further the paper ptosposed new concepts about the location of stratigraphy, lithofacies - paleogeography and the evolution of paleo-tectonics.
