摘要
本文系统地讨论了茅口期沉积层的发育特征,确定了茅口期地层顶、底及亚期界线.以单因素图件为基础,结合其它成因标志,编制了茅口早亚期和晚亚期岩相古地理图,由此可以看出茅口期的岩相古地理特征及其演化历史.
Based on the discussion of developing characteristics of its sedimentary formation, the boundary of top and bottom of Maokou Age formation and substage is set up. The lithofacies paleogeographic patterns in Maokou early substage and late substage are worked out the basis of the single factor maps and combined with other facies indexes, through which the characteristics of lithofacies paleography of Maokou Age and their evolution can be seen.
