Part I: Outcrops
Here are 9 outcrops of rocks that show sedimentary structures of some kind. Thoroughly explore each scene to determine which sedimentary structures are present. (1) Identify them, and then (2) interpret them [i.e., (a) how they formed, (b) what they reveal about geopetal “up” direction or current direction].
Part II: Hand samples
Examine these 19 samples of rock showing various sedimentary structures and: (a) identify them and (b) interpret them.
(Note: The little black curled lines here are the shells of small arthopods –shrimplike creatures– called ostracodes. Consider these hemispherical structures as sedimentary particles, as you would grains of sand.)
Sample 11: (FYI, the little dash-shaped features that mainly run from left to right are gypsum casts)
