Episodic kilometre-scale burial and exhumation and the importance of missing section
P Green, I Duddy, P Japsen - Earth-Science Reviews, 2022 - Elsevier
The incompleteness of the stratigraphical record is well documented, and the concept of
“missing time” has attracted renewed attention in recent years. However, the importance of …

Macrostratigraphy: insights into cyclic and secular evolution of the Earth-life system
Rocks in Earth's crust are formed, modified, and destroyed in response to myriad
interactions between the solid Earth (tectonics, geodynamics), the fluid Earth (ocean …

Phanerozoic flooding of North America and the Great Unconformity
AR Tasistro-Hart, FA Macdonald - Proceedings of the …, 2023 - National Acad Sciences
The flooding record of North America has been used to infer patterns of global erosion and
