根据岩石组合,古生物组合,沉积构造及剖面结构,将贵州早二叠世沉积相划分为四个相区、九个相带,它们是: 1.滨岸漫滩沼泽相 Ⅰ.陆地边缘相区 2.潮汐泥坪相 3.潮坪沼泽相 4.半局限台地相带 Ⅱ.碳酸盐台地相区 5.开阔台地相带 6.较深水台沟相带 7.碳酸盐合地边缘生物滩相带 Ⅲ .碳酸盐台地边缘相区8.碳酸盐台地边缘生物礁相带   Ⅳ.浅海盆地相区 9.浅海陆棚相带。 贵州早二叠世经历了一个完整的海进海退旋回,茅口早期是最大的海侵期,就沉积的演化而言,它大体经历了两个阶段。即第一阶段(栖霞早期)系清水和浊水混合的缓坡型沉积,其特征是:1.碳酸岩与碎屑岩共同发育;2.碳酸盐台地边缘礁滩相不发育。第二阶段(栖霞晚期至茅日晚期)为清水碳酸盐台地沉积,特征是:1.主要为碳酸盐岩,2.碳酸盐台地边缘生物滩礁带发育。

According to the statistic graphs worked out from the biomechanicevolution of 48 types of cardinalia of Ordovician Orthida and the diversityof 200 Ordovician brachiopod genera in 5 main biogeographical regions ofChina, three destruction-construction periods corresponding to the threetransgression-regression cycles are recognized. They are represented by thethree turns of successions of dissipative-intrusive changes relative to theopen-close processes of the thermodynamic system. During the constructiveprocess the biomechanic evolution of cardinalia proceeded mainly instochastic changes without apparent functional evolution. The ecosystemcirculates and dissipates the energy and material leading to the increase ofdiversity. Such a process is described as "dissipative change". During thedestructive stage the diversity decreased suddenly and a number of speciesdisappeared, but the cardinalia evolved rapidly with the striking improve-ment in organic function, which indicates an action of dynamic selection.Such a strong change for the whole system under the intrusion of outerdynamic may be called the "intrusive change". Both changes are in mutualnegation to constitute the succession of the construction-destruction periodand reveal the basical evolutionary characters of the open system.

在统计我国奥陶纪5个主要生物地理区的200多腕足动物属的生态系统演化资料和奥陶纪正形贝目的近50类型主基构造演化资料的图表中,一致出现了三次破、建演化周期,它们正好对应三次海侵、海退旋回,显示与热力学系统开放、封闭相应的侵变、耗变三轮演替。进化就是这二对立演变相互否定的过程,动力选择和中性飘变,激进化和渐进化因而分别对应形成地史周期发展的这二对立演变而统一起来。

The Late Palaeozoic coal-bearing measures on the eastern margin of Ordos basin include Benxi fm, Jinshi fm, Taiyuan fm, and Shanxi fm, The coal-bearing measures are divided upward from bottom into ten cycles which laterally are persistent in the region according to the numbers of marine layers and the variation of sediment grains. All cycles are derived from the allocyclity,and mainly controlled by the regionally eustatic sea-level change. No. 1-3 cycles belong to Benxi fm and Jinshi fm. The open epicontinental...

The Late Palaeozoic coal-bearing measures on the eastern margin of Ordos basin include Benxi fm, Jinshi fm, Taiyuan fm, and Shanxi fm, The coal-bearing measures are divided upward from bottom into ten cycles which laterally are persistent in the region according to the numbers of marine layers and the variation of sediment grains. All cycles are derived from the allocyclity,and mainly controlled by the regionally eustatic sea-level change. No. 1-3 cycles belong to Benxi fm and Jinshi fm. The open epicontinental sea covered the north-middle tracts of investigative area when No.l-3 cycles were deposited, and the transgression was invaded from east or northeast and palaeoslope trended northward at that time. The Zhongtiao palaeouplift which exsisted the southern part of the studying area caused this two formation thickness to thin and pinch out southward. The open epicontinental sea was located in the south-middle tract of the studied area when No.4-8 transgressive-regressive cycles (belonging to Taiyuan fm and the lower members of Shanxi fm) deposited. The transgreesion was invaded from southeast and northward, and palaeoslope trended southward.

鄂尔多斯盆地东缘晚古生代含煤岩系包括本溪组、晋祠组、太原组和山西组,依据海相层的发育和沉积物粒度变化,自下而上可划分为10个区域上稳定的旋回。这些旋回属它旋回成因,主要受控于区域性海平面的变化。第Ⅰ~Ⅲ旋回为本溪组和晋祠组,其沉积时开阔的海域位于研究区的北、中部,海水由东或北东方向侵入。研究区南部存在的古中条隆起使这两组的地层厚度自北向南减小,古地形向北倾。第Ⅳ~Ⅷ为海侵—海退旋回(太原组和山西组下段)开阔海域位于研究区南、中部,各期海相层由南、中部的灰岩向北变为泥灰岩、泥岩,在研究区北部最终尖灭。海水是从南东方向侵入的。各期海退碎屑沉积物由北部的河流沉积体系向南变为三角洲沉积体系,在南部为潮坪—潮道或沙坝体系,古海岸线逐渐南移。聚煤中心位于各期古岸线的附近或前方,并随时间的推移而向南移。
