摘要：
The Late Paleozoic ice age is a vital event in the geological history. The sea level change caused by the Late Paleozoic ice age has a far-reaching impact on the reef system. The response of reefs to sea-level change in the context of the Late Paleozoic ice age is discussed. Reefs exhibit three primary modes of response：“abandonment”，“synchronization”，“persistence”. We calculated the rise of sea level in Gzhelian by the large Bianping coral reef in southern Guizhou. The sea level of Gzhelian in southern Guizhou rose by about（60±5）m，which is mainly caused by glaciation. The sources of error in this estimation chiefly revolve around basement subsidence and inaccurate estimation of paleo-water depth. The morphology and rapid growth characteristics of Fomitchevella reveal the paleoenvironmental conditions of warm climate，rising sea level and rapid transgression in the Gzhelian period in southern Guizhou. The development of the Bianping coral reef reflects the global climate change and sea level fluctuations are related to the ice age. © 2024 Northeast University. All rights reserved.
