Submarine‐channel meandering reset by landslide filling, Taranaki Basin, New Zealand
Submarine channels offshore New Zealand were filled with mass transport deposits and this resulted in a reset of the systematic migration of the channels
Stratigraphy
Automated multi-well stratigraphic correlation and model building using relative geologic time
Stratigraphic correlation of geophysical well logs is one of the most importantand most time-consuming—tasks that applied geoscientists perform on a daily basis. Using the dynamic time warping (DTW) a…
Stratigraphic correlation: Old concepts inform new approaches
In this talk, I first want to revisit and visualize the basic ideas about how time is recorded - or not recorded - in sedimentary deposits and then show how chronostratigraphic diagrams can be used as key elements of an automated workflow for correlating geophysical well logs.
Channel trajectories control deep-water stratigraphic architecture
Interpretation of deep-water channel deposits is challenging because the spatial arrangement of their constituent lithologies is highly variable. This variability is often thought to be a signature of…
Chronostratigraphic diagrams revisited: Visualization and correlation in the time domain
We use experimental data from the ‘Jurassic Tank‘ flume (St. Anthony Falls Laboratory) to create three-dimensional chronostratigraphic diagrams, compute stratigraphic completeness, and test several sequence stratigraphic concepts.
The three-dimensional geometry and stratigraphic record of meandering
This presentation explores the dynamics of meandering systems in both fluvial and submarine environments, focusing on the predictability of channel migration and the resulting stratigraphic heterogeneities.
