Highstand deposits consist of a thick wedge of fine-grained, skeletal and non-skeletal sands and carbonate muds derived predominantly from the platform and deposited on slopes of 25-28°.carbonate platforms, it is concluded that the inun dation of carbonate platform was mainly the result of terrestrial debris input and water eutrophication [10,14,15,3 7,38]. Therefore,The isolated carbonate platform is recognized based on diagnostic criteria defined by (Burgess et al. 2013) such as a positive antecedent topography, marked stratal thickening, high angle flanks, stacking patterns, distinct reflection amplitude, and geometry, and onlaps of surrounding sediments. Middle to Late Miocene time has witnessed the ...Carbonate platforms and reefs emerge, grow and die in response to intrinsic and extrinsic mechanisms forced primarily by tectonics, oceanography, climate, ecology and eustasy. These mechanisms, or controls, create the physical, biological and chemical signals accountable for the myriad of carbonate depositional responses that, together, form ...
