Résumé partiel
There are different studies discussing the Barzaman Formation in the UAE and sw Oman while outcrops exposed in North Oman are not studied in detail. The aim of this study is to construct detailed lithostratigraphic columns with correlations and documenting a Miocene syndepositional thrust, instable slope sediments, identifying the depositional environments and studying the diagenesis. The field observations, laboratory microscopic analyses of (25 thin sections) and XRD (X-Ray Diffraction) a nalyses of 8 samples have been used for the correlation between different logs by recognizing the similarity in lithology, mineralogy, and fossils contents and for determining the depositional environments and the depositional history. The observed thickness of the exposed Barzaman Formation within the SQU campus as represented in the measured sections amounts to 91.3 m, which is not the maximum value for this formation. By integrating all methods, the Barzaman Formation has been divided into five levels, according to the similarity in lithology and depositional environments. These levels are : the (1) lower conglomerate and sandstone facies, (2) carbonate facies, (3) varied thick sandstone and conglomerate facies, (4) claystone (palygorskite) and conglomerate facies, and (5) dolomitic conglomerate facies.
