石炭系维宪阶-谢尔普霍夫阶全球界线层型尚未确立。由于石炭纪冰期效应显著,海平面升降频繁,造成沉积环境发生剧烈变化,给该界线的划分和对比带来了一定困难。罗悃剖面位于贵州省罗甸县西南,出露维宪阶上部至莫斯科阶上部的一套上斜坡相深水碳酸盐岩沉积,受水深影响较小,同时产丰富的牙形刺及有孔虫,可以较好地进行深、浅水相区的对比。本文通过对该剖面维宪阶—谢尔普霍夫阶界线层较为详细的采样分析,共发现牙形刺8属32种(含9亚种和1未定种),自下而上识别出两个牙形刺带,即Lochriea nodosa和L.ziegleri带,将谢尔普霍夫阶底界置于L.ziegleri的首现面,即罗悃剖面4.65m处;同时与同属华南的纳庆剖面以及全球其他地区重要剖面的牙形刺带或菊石带进行了对比。 The Carboniferous Uygur Autonomous-Serpukhov Stratum has not yet been established. Due to the significant effect of the Carboniferous glacial period and the frequent sea level rise and fall, the sedimentary environment changed drastically, which brought some difficulties to the division and comparison of the boundary. Located in the southwest of Luodian County in Guizhou Province, the Luohe section shows a set of upper-slope facies and deep-water carbonate deposits from the upper part of the Vignian order to the upper part of the Moscow Stratum. It is less affected by the water depth and produces abundant conodonts and holes Insects, can be better for deep, shallow water area contrast. In this paper, a more detailed sampling analysis of the Chebyshoff level boundary layer is carried out. A total of 32 species (including 9 subspecies and 1 undetermined species) of 8 genera of conodonts are found, and two teeth are identified from the bottom up Shaped spines, namely Lochriea nodosa and L.ziegleri belts, place the top of the Serpukhov at L.ziegleri’s foreside, which is 4.65 m at the Loquat section. At the same time, they are also associated with the Nahon profile that belongs to southern China and other parts of the world An important section of the conodont tape or ammonite was contrasted.
