1979-IV-A-4/2, Idri Fmn., Ash Shati area, N. flank of Murzuk Basin (Devonian of Libya)

Where: Libya (27.5° N, 13.1° E: paleocoordinates 50.5° S, 36.6° E)

• coordinate estimated from map

• outcrop-level geographic resolution

When: Idri Formation, Givetian (387.7 - 382.7 Ma)

• Age range of formation is Givetian to early Frasnian (ref. 8780). However, the bulk is Givetian.

• bed-level stratigraphic resolution

Environment/lithology: marine; sandstone and silty claystone

• BA 3; fossils occur chaotically in sst; subtidal, rough water
• Formation in general: "In the type area, the Fm. consists of fine-to-med.-gr sst. and of two layers with prevailing silty clayst (one of them at the bottom of unit). Towards the east, the silty-argillaceous layers wedge out and the sst become prevalently cross-bedded."
