Reservoir-scale heterogeneity in Upper Miocene Platforms of the Balearic Islands.
The objective of this field trip is to understand the factors that control facies belts distributions, platform architecture and internal distribution of heterogeneities.
The first part of the course covers a Lower Tortonian depositional sequence consisting of a transgressive systems tract (nearshore carbonates onlapping and backstepping onto Neogene and Mesozoic rocks) and a highstand systems tract (HST) that corresponds to an aggrading and prograding, high-energy, distally steepened ramp. The second part concentrates on an Upper Tortonian / Lower Miocene depositional sequence comprising a prograding, reef-rimmed platform resulting from euphotic carbonate production by a framework-dominated reef system.
