Sedimentary Structures

Sedimentary structures and bedding patterns provide invaluable information related to current conditions and suitability for past life (e.g., oxygen content of bottom waters and stability of the bottom in terms of storm waves passing through). The sedimentary structures shown below are commonly seen in both clastic and carbonate sediments.


Tabular and lensoidal beds; sharp and gradational contacts

Graded Bedding
(normal and reverse)
Ripples and Dunes
Mud cracks
(animal burrows and trails)
