Carboniferous Sequence Stratigraphy and Glacio-Eustasy of Triticites Zone in Southern Guizhou, China

Liu Benpei Li Rufeng You Dehong (China University of Geosciences, Beijing 100083)  
Based on the outcrop sequence-stratigraphic analysis of the typical Carboniferous carbonate sections exposed from southern Guizhou, 10 third-order sequences are examined in detail with particular attention to the key surface or the parasequence stocking pattern respectively. There are 2 sequences in Tournaisian (Datang), 3 in Visean -Early Namurian (Yanguan), 2 in Late Namurian-Westphalian (Weining )and 3 in Stephanian-Sakmarian (Maping). Most of these sequences can be correlated in various paleogeographic units and sedimentary fades. It should be pointed out that 17 fourth-order glacial-eustasy trans-gressive-regressive cycles of the Triticites zone are found both in the southern Guizhou and in the North American Midcontinent. In Midcontinent, these cydes are represented by fourth-order sedimentary sequences; but in the Southern Guizhou, only parasequences. Probably,the same eustasy and the different tectonic background are the main causes of above facts during the Stephanian.
