Utah State University: Fluvial Fingerprints: Major New Database Tracks Sediment Across Mississippi River Basin. “Tracking the sources of excessive sediment in the Mississippi River Basin (MRB) has proven to be a vexing and economically important question for the last few decades … Now, the first basin-wide sediment fingerprinting database makes it possible to track where sediment is coming […]

The abstract submission deadline for the @EuroGeosciences meeting is coming up soon, and if you are thinking about submitting anything on #diagensis or reactions in the #sediment, consider our session (SSP3.9) where we ask:
What if the most important setting for carbonate diagenesis is the first few meters below the seafloor?

What if the most important setting for carbonate diagenesis is the upper few meters of the sediment pile, in marine pore waters, not the deeper burial or meteoric realms? If correct, this is a paradigm shift in how we understand marine chemical fluxes, limestone formation, the marine fossil record, and sediment budgets. We invite contributions from all disciplines, from modern to ancient carbonates, laboratory, and modelling approaches, focusing on understanding this under-appreciated geochemical setting and also the broader impacts for Earth system studies.

A graded bed and the start of the next one in a Silurian greywacke, Appalachians. The mostly quartz and plagioclase grains get finer to the left, indicating that 'up' was to the left as the grains settled in the water column.

A thin section imaged in plan-polarized light. The big clear grains are quartz, and get finer to the left, before abruply coarsening again. The original 'up' was to the left.
