2079-I-A-2, Ashkidah Fm., Ash Shati area, N. flank of Murzuk Basin (Devonian to of Libya)

Where: Libya (27.5° N, 13.9° E: paleocoordinates 37.6° S, 19.2° E)

• coordinate estimated from map

• outcrop-level geographic resolution

When: Ashkidah Formation, Famennian to Famennian (372.2 - 346.7 Ma)

• bed-level stratigraphic resolution

Environment/lithology: marine; sandstone and hematitic siltstone

• Mergl and Massa consider the environment similar to that of the Tarut Formation (shallow, lagoonal, BA 1).
• Formation as a whole: "...mostly consists of fine-grained sandstone, siltstone and claystone alternating in various proportions. In the central and eastern parts of Wadi ash Shati, the ore-bearing member "B" developed amidst the Fm., dividing it into a lower, a middle, and an upper part...Fossil fauna is very scarce in the bulk of the Fm.." This collection: "very base: hematized siltstone above iron-ore A"
