This exploration defines the new Dapingian Stage with clear stratigraphic layers in the Huanghuachang section, demonstrating its geological importance.
Key evidence includes distinct stratigraphic markers that characterize the Dapingian Stage's unique features and its paleoenvironment.
Analysis of geological formations reveals crucial insights into Ordovician sea-level changes and biodiversity during this period.
This work highlights the need for global agreement on geological stages to enhance understanding of Earth's history.
