Mdeyrij-Hammana, Casa Baabda (Azar coll) (Cretaceous of Lebanon)

Also known as Lebanese amber

Where: Lebanon (33.8° N, 35.7° E: paleocoordinates 9.4° N, 31.9° E)

• coordinate based on nearby landmark

• outcrop-level geographic resolution

When: Late/Upper Barremian (130.0 - 125.5 Ma)

• Amber found in three intervals in the upper part of the Grès du Liban. Hammana is found in the upper interval, located between the Jezzinian above and the "Banc de Mrejatt" below. The "Banc de Mrejatt" includes one biostratigraphically significant benthic foraminifer: Eopalorbitolina transiens (Cherchi and Schroeder, 1999), which is a zonal marker of the Lower to Upper Barremian transition according to Schroeder et al. (2010). Accordingly the “Banc de Mrejatt” is correlated to the transgression of sequence Ba3 of Clavel et al. (2007) and ascribed a late Early Barremian age. The upper subunit is assigned a Late Barremian age, although the amber may be reworked (Maksoud et al., 2016).
