1979-IV-A-20, Idri Fmn., Ash Shati area, N. flank of Murzuk Basin (Devonian of Libya)

Where: Libya (27.4° N, 13.2° E)

• Paleocoordinates: 46.4° S, 10.2° E (Wright 2013)

• 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 2
• 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." This coll.: fine-gr. sst [ref. 9606].
