Eighteen cycles of sea level rising and falling are recognized in Devonian in Longmen Mountains , western Yangtze. They are superposed to be three para 2nd order cycles and one 2nd order cycle, in which four types of frequency (Fm) - amplitude (Am) of sea level rising and falling can be distinguished as low Fm - low Am, high Fm - low Am, low Fm - high Am, and high Fm - high Am. The Devonian relative sea level changes in time gradient, the characteristic of undulation from gentle rising and long duration to stable falling and short duration are consistent with those all over the world at the same time, although the stratigraphic horizon of the highest and lowest stands are different. The highest stand horizon in Longmen Mountains, the Tuqiaozi Formation, is in the mid lower asymmetricus zone in the early Frasnian that is lower than that in western Qingling Mountain, Euramerica , and higher than that in southwestern Siberia; the lowest stand horizon, the top of Pingyipu Formation, is roughly in the mid upper kindlei zone in Pragian which is earlier than that in Euramerica , Siberia and South China. At the end of the paper, some problems and significances on the pattern, frequency, amplitude and benthic water depth curve are discussed.

龙门山地区泥盆纪海平面升降由三个准二级旋回叠加组成:第一个含S1~S3层序所对应的三个海平面升降旋回;第二个、第三个分别含S4~S10六个和S11~S18八个层序映射的三级海平面组合而成。海平面升降频幅样式可识别低频低幅、高频低幅、低频高幅、高频高幅四种类型,整个泥盆纪表现为早晚期低频低幅型,中期则以另外三种混合叠加为主。最高、最低海平面对比显示全球各大陆具不等时性,全球海平面升降规程则具相似性。

The patterns of lithofacies sequence for the high frequence cycles can be divided into three ways as the asymmetric upward shallowing, the asymmetric upward deepening, and symmetric fluctuation.

There are eighteen 3rd order depositional cycles recognized in the Devonian of Longmenshan aera which are stacked to three para 2nd order cycles and one 2nd order cycle, and a lot of high frequence cycles with complicated lithofacies sequences are distinguished too. The patterns of lithofacies sequence for the high frequence cycles can be divided into three ways as the asymmetric upward shallowing, the asymmetric upward deepening, and symmetric fluctuation. The high frequency cycles in the transgression of the 2nd order cycle are changed from dominant allocycles to autocycles, and those in the regression are predominative of autocycles.

扬子西缘龙门山地区泥盆系可识别出一个二级、三个准二级、十八个三级沉积旋回和三十余种高频旋回,低级(高频)旋回往往以不同形式叠加构成高一级沉积旋回。高频旋回具有复杂的相序结构样式,大致可概括为非对称向上变浅、加深和对称型三种。整个泥盆纪沉积旋回的旋回演化作用早期为异旋回作用,中期为自旋回与异旋回作用交替,晚期则转变成自旋回作用为主。

The Chuxiong Basin was a foreland basin on the southwestern margin of the Yangtze platform during the Late Triassic. The basin floor deformation of the foreland upwarped basin in the western part once led to a relative rise in sea level, and thus to three phase marine floodings during the Carnian and Rhaetian. Then these marine floodings prograded gradually toward the uplifted zone and cratonic margin in the eastern part, resulting in the deposition of the flooding sediments of carbpnate ramps and dark mudstones...

The Chuxiong Basin was a foreland basin on the southwestern margin of the Yangtze platform during the Late Triassic. The basin floor deformation of the foreland upwarped basin in the western part once led to a relative rise in sea level, and thus to three phase marine floodings during the Carnian and Rhaetian. Then these marine floodings prograded gradually toward the uplifted zone and cratonic margin in the eastern part, resulting in the deposition of the flooding sediments of carbpnate ramps and dark mudstones and shales. The progradation of the marine flooding bodies and coastal downlap in turn allow the formation of the composite depositional systems consisting of the Chuxiong delta and subaqueous sandy and gravelly lobes. The delta complexes in the foreland basin appeared during the falling phases of sea level, and are quite different from the passive continental marginal sequences. In the case of the conposite depositional systems, the condensed sections are less developed due to the covering of the transgressive surfaces by the downlap surfaces. These depositional systems are well represented by wedges and lobes. The sequence correlation is based on such indicators as three key boundaries, exposed unconformities, marine flooding onlaps and downlaps plus the features and types of subaqueous lobes and flooding bodies. Three sub second order sequences have been identified just by these indicators.

晚三叠世楚雄盆地是扬子西南缘的前陆盆地,其西侧的前陆挠曲盆地盆底变形导致海平面相对上升,从而在卡尼期和瑞替期有3 次海泛,并向东侧的前陆盆地隆起带和克拉通边缘推进,沉积了前陆碳酸盐缓坡和暗色泥页岩海泛物。由于海泛体的推进和海退下超的双重作用,构筑了楚雄三角洲与水下砂砾质舌形体组成的复合沉积体系。前陆盆地三角洲复合沉积体发生在海平面的主体下降阶段,与被动大陆边缘层序迥然有别,对比标志也各异。复合沉积体系的特征由于海退下超面掩盖了海侵面,因而凝缩层不发育,其时空展布则呈进积型迁移,沉积体系域多为楔形体和朵状体。层序对比的标志∶一是据3 个关键界面的特征,包括暴露不整合面、海泛上超面和洪泛下超面;二是水下舌形体和洪泛体的性质和类型,依此划分了3 个准二级层序
