FIDS: multiple structures

3D Model

Flow-induced Interfacial Deformation Structures (FIDS): polygonal structures & longitudinal ridges and furrows, also with prod and skim marks.

Carboniferous Bude Formation, Upton Beach, North Devon, UK. (50.81612 -4.55666)

The outcrop is c. 2.0m long x 0.45m wide, and the undersides of the beds show: 1 & 2: polygonal structures; 3 & 4: longitudinal ridges and furrows, and 5: prod and skim marks.
