Biosedimentology

How does life affect the sedimentary record, and visa versa? Similar to "microbe-mineral interaction," we study the larger scale interaction between life and sediments from the Archean to the recent. In carbonate settings, stromatolites, thrombolites, and other microbialites are the focus, while in siliciclastic settings, wrinkle structures left behind by microbial mats are key. In addition, we study the larger scale effects of life-sediment interaction through time (e.g., the Cambrian Substrate Revolution, and the effects of mass extinctions on biosedimentology, diagenesis, and paleoecology).
