Microfacies and Sedimentary Environment of Triassic Rocks in Eghlid Area (Fars Province)

Triassic rocks in Zagros zone, consisting of limestones, dolostones and shale (ca. 324 m thick), were examined in Eghlid area (near Nezamabad Village). A lithofacies (shale/marl) and 13 carbonate microfacies, consisting of: 1) paleosol, 2) supratidal mudstone, 3) algal mat boundstone, 4) intertidal mudstone, 5) intertidal breccia, 6) lagoonal mudstone, 7) shale/marl, 8) lagoonal mudstone/wackstone, 9) lagoonal wackstone, 10) lagoonal wackstone/packstone, 11) lagoonal packstone 12) sand shoal packstone, 13) sand shoale grainstone, and 14) open marine mudstone were recognized. All of them have been taken place in the inner part of a ramp. Microfacies 1 to 5 belong to intertidal zone; Microfacies 6 to 11 (and shale) occurred in the lagoon site; Microfacies 12 and 13 referred to the sand shoal and bar; and Microfacies 14 was deposited in the open marine belt of the sedimentary basin.
