根据“系”级年代地层界线应该是反映重要的地球历史发展阶段的自然界线的原则,本文主张以Gattendorfia带之底和Montiparus(或Obsoletes)带之底分别作为石炭系的下界和上界。根据在连续海相剖面上所观察到的多门类生物的自然发展阶段性及中国区域地质发展的阶段性特征,提出中国石炭系年代地层系统的新建议——分为三统八阶,自下而上为:下统革老河阶,刘家塘阶;中统新村阶,连南阶,上司阶,德坞阶和上统滑石板阶,达拉阶。
According to the “strata” stratigraphic boundaries should be an important reflection of the natural history of the Earth’s development stage of the principle of the line, this paper advocates the bottom of the Gattendorfia and Montiparus (or Obsoletes) with the bottom respectively as the Carboniferous lower and upper bounds. Based on the natural stages of development of multi-species organisms observed in the continuous marine facies profiles and the periodic characteristics of regional geological development in China, a new proposal of the China Carboniferous chronostratigraphy system is proposed The upper is: the lower reaches of the old river, Liuatang order; the new village order, and even the South, the superior, the German dock and the upper talc, Dalai.
