WebJan 25, 2024 · Herrera and Riggs (Citation 2013) observed that undergraduate students struggled with base level and eustasy concepts, which underpins the concept of correlative conformities. Since this concept is associated with sequence diagrams, this is the first time students would encounter correlative conformities in their geologic training. WebJul 1, 2010 · Forty years ago, the Quaternary community was ready to revise the old concept of eustasy and begin observation-based research, in which one could only define regional eustasy, not global eustasy. This should also apply for pre-Quaternary sea level research. Unfortunately, this is not yet the case.
