Description of Seismic Facies in Persian Gulf's Sediments, North of Qeshm Island

Using high-resolution shallow seismic data, we have investigated the seismic facies in northern Qeshm Island waterways in East of Persian Gulf. Seismic data obtained with Sub-bottom profiler and then interpreted by ISE software. Studies lead to recognizing 7 types seismic facies on seismic data. These facies are detectable by amplitude, continuity, geometry, internal pattern and staking pattern from each other. Results show that seismic facies formed in two various environments condition. Lower part facies have low amplitude with high lateral continuity and sustainability; but upper seismic facies have various amplitude with low lateral continuity. These facies have deposited in five periods that separate with erosional surfaces. Changes of depositional environments and province region of sediment supply can be realize from seismic facies. So, through deposition of LAP-C and MAC facies sediments have supplied from Qeshm Island; but, at the time of deposition of LAC and HAC sediments interred from the North.
