A. ooids
B. fossiliferous micrite
C. reef breccia
D. stromatolites
E. dinosaurs

Answer :

Final answer:

Typical features of carbonate depositional environments include ooids, fossiliferous micrite, reef breccia, and stromatolites.

Explanation:

Typical features of carbonate depositional environments include:

  1. Ooids: These are small spherical particles composed of concentric layers of calcium carbonate that form in warm, shallow marine environments.
  2. Fossiliferous micrite: Micrite is a type of limestone consisting of very fine calcite particles. Fossiliferous micrite contains abundant fossil remains, such as bivalves, corals, and trilobite imprints.
  3. Reef breccia: This is a type of rock formed by the cementation of fragmented coral and other reef organisms.
  4. Stromatolites: These are layered structures formed by the growth of cyanobacteria (blue-green algae) in shallow, warm waters.
