Wet, dry, and stabilized dune systems
Aeolian systems exist as a dynamic continuum that, for convenience, are assigned dry, wet, and stabilized end members. Aeolian dunes […]

Experimental sequence stratigraphy: model results
The experiment at the Experimental EarthScape facility focused on evaluating sequence stratigraphic discordances in a scale-independent sedimentary basin model. Key findings included significant stratigraphic surfaces like downlap and onlap, generated during base level changes. The results align well with natural stratigraphic systems, showcasing the importance of base level dynamics in sedimentary processes.

Experimental sequence stratigraphy: model attributes
This post discusses an experimental stratigraphic modeling process conducted at Minnesota University’s Experimental EarthScape facility. It highlights the methods, boundary conditions, and variable base levels used to analyze sedimentary systems and stratigraphic responses, building on previous research by Martin et al. and emphasizing the importance of controlling various factors.
