Morphologies of these stromatolites include laminar, wavy-laminar, domal or hemispheroidal, bulbous, and flabellate-growth columns. Individual stromatolites are generally 3–6 cm thick, which can grow upward upto 60 cm thick in the core facies. The core-facies of stromatolite mounds were formed by calcimicrobes, with initially horizontal laminar and tabular growthforms later becoming domal and bulbous forms, and finally flabellate columnar forms indicating a gradual relative sea-level rising. The occurrence of talus breccias under and above themounds suggests that they were located at a deep slope setting.
