The stratigraphic record is famously fragmentary, but it is also full of short, relatively complete fragments — laminated siltstones, eolian cross sets, point bars — that record ordinary events at seasonal to annual resolution.
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.
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.
