Question

While observing a sedimentary rock outcrop, you note that majority of the material cemented in the stratigraphic unit is gravel-cobble in size, but poorly sorted and angular. From these basic observations, what can you infer about the depositional environment represented by the sedimentary characteristics?
a) locate in the lower reach of a meandering stream
b) located in a evaporitic, internally drained basin
c) located in a shallow marine environment on the continental shelf
d) located near the headwaters of a mountain reach of a stream
e) located in an estuarian environment

Answer 1

Answer: located in a shallow marine environment on the continental shelf.

Explanation: The illustrations shows that the sedimentary rock outcrop is a Conglomerates. Marine transgression above unconform structures initiates the base of the sequence laid down. They shows shoreline position at a specific time.
