Grain-Size and Discharge Controls on Submarine-Fan Depositional Patterns From Forward Stratigraphic Models

Submarine fans are important components of continental margins; they contain a stratigraphic record of environmental changes and host large accumulations of oil and gas. The grain size and volume of s…

Submarine channels ‘swept’ downstream after bend cutoff in salt basins

Channel‐bend expansion and downstream translation, as well as vertical movements by aggradation and incision, set the stratigraphic architecture of channelized depositional systems. Early work on subm…

Conversion of tectonic and climatic forcings into records of sediment supply and provenance

Understanding how environmental forcings (e.g., tectonics, climate) are transformed by erosional landscapes into sedimentary signals is a critical component of inverting the stratigraphic record. Prev…

High curvatures drive river meandering

One of the long- and widely held ideas about the dynamics of meandering rivers is that migration slows down in bends with higher curvatures. High-resolution measurements of migration rates of more tha…

detritalPy: A Python‐based Toolset for Visualizing and Analyzing Detrital Geo‐Thermochronologic Data

Detrital geochronology and thermochronology have emerged as primary methods of reconstructing the tectonic and surficial evolution of the Earth over geologic time. Technological improvements in the ac…

Slope-fan depositional architecture from high-resolution forward stratigraphic models

Submarine fans in tectonically active continental-slope basins are targets of petroleum exploration and pro- duction. These slope fans commonly comprise compensationally stacked sandy and muddy archit…
