CQ-21 - Carranques [San Adrian Mbr, Alba Fm] (Carboniferous of Spain)

Where: Spain (43.6° N, 5.8° W: paleocoordinates 9.3° S, 8.3° E)

• coordinate estimated from map

• small collection-level geographic resolution

When: Lochriea nodosa conodont zone, San Adrian Member (Alba Formation), Arnsbergian (327.0 - 323.7 Ma)

• STRATIGRAPHIC RELATIONS: From the San Adrian Mbr of the Alba Fm, which is overlain by the Barcaliente or Cuevas fms. The Cantabrian Alba Formation is correlated with nodular limestones of the Aspe-Brousset Formation in the Pyrenees (Perret 1993; Sanz-Lopez 2002). AGE: Arnsbergian, on the basis of conodont biostratigraphy; Lochriea nodosa conodont zone.

• bed-level stratigraphic resolution

Environment/lithology: lithified, black, gray limestone

• LITHOLOGY: Grey to black, often laminated, limestones. LITHIFICATION: Lithified, on the basis of preparation techniques used.

Size class: mesofossils

Collection methods: bulk, sieve,

• COLLECTOR: Presumably the authors. REPOSITORY: Department of Geology at the University of Oviedo (DPO), Spain.
