Several of the potential analogs seemed very divergent. How do you reconcile a buried soil/paleosol within a fluviolacustrine system?
Thanks for your question! A paleosol would indicate a period of low lake levels and exposure of sediments, in terrestrial lacustrine sequences you see paleosols when the shoreline moves inward. So the clay-rich sediments in Glen Torridon may have formed through the weathering of lacustrine sediments as the shoreline of the fluviolacustrine system fluctuated and because of that the clay-rich region we see today could represent a clay-rich soil horizon/paleosol.
