Maaseik Well (49W0220) - 276 m (Berada Fm) (Miocene of Belgium)

Where: Belgium (51.1° N, 5.8° E: paleocoordinates 51.3° N, 4.5° E)

• coordinate based on nearby landmark

• small collection-level geographic resolution

When: Antwerp Member (Berada Formation), Serravallian (13.8 - 11.6 Ma)

• STRATIGRAPHIC RELATIONS: From the "Upper Antwerp Sand" of the Berada Fm, which is overlain by the Kieseloolith Fm (Pliocene). Equivalent to the Antwerpen Mbr and Zonderschot Mbr of the Berchem Fm. THICKNESS: From <1 m thick horizon, within core. AGE: Middle Serravallian (latest Middle Miocene), based on dinoflagellate biostratigraphy. STRATIGRAPHIC POSITION: From near base of core.

• bed-level stratigraphic resolution

Environment/lithology: coastal; unlithified sandstone

• ENVIRONMENT: Not reported in available text, but apparently shallow marine, siliciclastic setting.
• SPECIFIC LITHOLOGY: Very fine sand. LITHIFICATION: Unlithified.

Size class: macrofossils

Collected by G.S. Belgium in 1980

Collection methods: bulk, core, sieve,

• COLLECTORS: Geological Survey of Belgium (1980). REPOSITORY: IRScNB/KBIN collection, Dept. of Paleontology, section Invertebrate Paleontology, Geological Survey of Belgium. COMMENTS: Sieved on a 0.5 mm mesh and all identifiable fragments of mollusca were collected.
