Sedimentologic and diagenetic controls on pore-network characteristics of Oligocene–Miocene ramp carbonates (Majella Mountain, central Italy)
This article addresses the controls exerted by sedimentologic and diagenetic factors on the preservation and modification of pore-network characteristics (porosity, pore types, sizes, shapes, and distribution) of carbonates belonging to the Bolognano Formation. This formation, exposed at the Majella...
