Carbonate mud mound - Aferdou el Mrakib (Devonian of Morocco)

Also known as Reef 1567

Where: Morocco (30.8° N, 4.5° W: paleocoordinates 44.5° S, 15.7° E)

• coordinate based on nearby landmark

• outcrop-level geographic resolution

When: Givetian (387.7 - 382.7 Ma)

• Mader Basin

• bed-level stratigraphic resolution

Environment/lithology: reef, buildup or bioherm; mudstone

• Aferdou el Mrakib

•Orientation: N-S

•Length: 1200m

•Width: 1000m

•Elevation: 250m (including 100m now eroded off the top)

•The mound facies is a thick-bedded to massive wackstone, floatstone or (locally) boundstone with varying amounts of skeletal debris. Frame builders occur only patchily in situ and are most common in the largest mound (Aferdou el Mrakib).

Size classes: macrofossils, microfossils

Preservation: original calcite

Collection methods: peel or thin section,
