Comparison of Tidalites in Siliciclastic, Carbonate, and Mixed Siliciclastic-Carbonate Systems: Examples from Cambrian and Devonian Deposits of East-Central Iran

Figure 9

Field photos and photomicrographs of stromatolite and associated sedimentary structures in the carbonate tidalites. (a) Cross section of planar and domal stromatolites in the Deranjal Formation. (b) Domal stromatolite (small scale) in the Deranjal Formation. (c) Boundstone microfacies (stromatolitic) in the Deranjal Formation. (d) Large-scale domal stromatolite. These structures are made up of small-scale stromatolites community. (e) Field photo shows that domal stromatolites are often the last layers of channel deposits. (f) Close-up view of planar stromatolite in the Deranjal Formation. (g) Cross section of domal stromatolite in the Deranjal Formation (close-up view). (h) Photo of stromatolite structures in the Padeha Formation. (i) Tepee structures in the Padeha Formation (without crest fracturing). (j) Tepee structures associated with stromatolite in the Padeha Formation (with crest fracturing (arrow)).
