The outcrop of this GSSP extends from the Middle Permian Gufeng Formation to the middle portion of the Nanlinghu Formation in the Lower Triassic Series. The more intact section extends from the upper part of the Lungtan Formation of the Permian Series to the lower part of the Nanlinghu Formation. The sequence of the Lower Triassic Series and its associated lithological cycles are very clear. Notwithstanding the steep terrain, the rock strata are aligned and have a constant thickness. The mudstone in the upper part of the Yinhang Formation and the Lungshan Formation strata include prominent sequences than can be correlated with those in the Majiashan area. This section is the most representative marker of the middle and lower strata of the Lower Permian Series in this region. The research on the Induan-Olenekian boundary is more precise and has led to more accurate records. The Lower Triassic Series in the Chaohu area clearly contains eight conodont and ammonite zones that have...
