Abstract: | The Asmari Formation is a thick carbonate succession of the Oligo-Miocene in Zagros Mountains (southwest Iran). In order to
interpret the facies and depositional environment of the Asmari Formation, three measured sections were studied in Fars area
for microfacies analyses. There, 12 microfacies types are distinguished based on their depositional textures, petrographic
analysis, and fauna. Thus, three major depositional environments were identified in the Asmari Formation including open-marine,
reef/shoal, and lagoon. These depositional environments correspond to inner, middle, and outer ramp. |
