1979-IV-D-12/2, Idri Fmn., Ash Shati area, N. flank of Murzuk Basin (Devonian of Libya)

Where: Libya (27.4° N, 13.1° E: paleocoordinates 50.6° 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

• 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."
