This document discusses the interpretation of sedimentary structures and their relationship to depositional environments and flow regimes. It provides examples of how different sedimentary structures like cross-bedding, ripples, and parting lineations can indicate specific depositional processes and environments like river channels, wave activity, or turbidity currents. Models are presented showing how the succession and variation of sedimentary structures in a sequence can be used to interpret changes in flow velocity, depth, and grain size over time. These principles are applied to examples like point bar deposits and Bouma sequences to reconstruct paleoenvironmental conditions.
