Various Pore Types in a Paleocene Reef, Banija, Yugoslavia
Various pore types and their fillings are described and related to the processes in the developmental history of a Paleocene reef exposed near Banija, Yugoslavia. Several pore types are recognizable and include: 1. large spaces between biolithic constructions, 2. small growth cavities, 3. intraskeletal pores, 4. cavities produced by organic borings, 5. skeletal moldic pores, 6. solution cavities, and 7. fissure cavities. Organic growth and encrustation, internal deposition and cementation are regarded as constructional processes in pore formation whereas abrasion, organism borings, dissolution and fracturing represent destructive processes that produced and modified various types of pore spaces. Included in this discussion is an outline of the paleogeography and depositional history of Paleocene marine carbonates in the Banija region of Yugoslavia.
