Zeimlet Formation, Marhouma Section (Devonian of Algeria)
Where: Algeria (30.0° N, 2.1° W: paleocoordinates 65.7° S, 34.0° E)
• coordinate based on nearby landmark
• local area-level geographic resolution
When: Zeimlet Formation, Lochkovian (419.2 - 410.8 Ma)
• formation-level stratigraphic resolution
Environment/lithology: offshore; shale and limestone
• SEP environmental call based on given information and, more importantly, interpretation of sections in secondary ref.
• Section of Legrand (1977) (ref. 7519, fig. 2) indicates shale ("argile") with limestone interbeds. Legrand indicates that the formation is more argillaceous here than elsewhere.
