Problem: Describe in detail the features including:
- Grain size, sorting, texture, composition, sedimentary structures, fossils, etc.
- How you determined it was indeed sedimentary. Note also that preexisting igneous, metamorphic or sedimentary rocks may comprise part of the grain composition in your sedimentary rock of choice; per the concept of the rock cycle.
- How and in what type of depositional environment this rock may have formed?
- How has plate tectonic or local structures (folds/faults) contributed to the making of the sedimentary basin where this rock was deposited?
