3. Large Scale Cross Stratification

4. Graded Bedding Rapid deposition of suspended sediment
Commonly associated with turbidity currents
Occurs in may depositional environments

5. Halite and Gypsum Crystal Molds, Casts and Pseudomorphs
Evaporation concentrates brine. Evaporite minerals precipitate and displace surrounding sediment. Later, evaporites dissolve or are replaced by less soluble minerals.

6. Symmetrical Ripples

7. Oriented Fossils
Elongate fossils are aligned by currents post mortem.

8. Tool Marks vs. Striations
