The deep-water Léopard gas discovery in offshore Gabon presents an opportunity to examine distal facies of the Albian Madiela and Cap Lopez Groups, which overlie the Aptian Ezanga Salt. In proximal settings, the Madiela (Azingo Formation) consists of shallow marine limestone and has sparse foraminiferal recovery. In contrast, planktonic foraminifera assemblages are typically abundant and reasonably diverse in the interbedded calcareous claystones, marls, and limestones of the distal equivalent (Namina Formation) penetrated by the Léopard discovery and appraisal wells. Five informal local planktonic foraminiferal biozones are interpreted, listed from youngest to oldest, as follows: (1) an Early Cenomanian–Late Albian Muricohedbergella delrioensis “Partial-Range Zone,” characterized by abundant Muricohedbergella delrioensis and a diverse benthic foraminiferal assemblage; (2) a Late Albian Ticinella spp. “Highest-Occurrence Zone,” defined by top Ticinella primula and Globigerinelloides bentonensis; (3) a Late–Middle Albian Favusella spp. “Highest-Occurrence Zone,” defined by the top of common Favusella washitensis and containing the additional top of Microhedbergella pseudoplanispira; (4) the Early Albian Microhedbergella rischi “Highest-Occurrence Zone,” defined by the top of Microhedbergella rischi and associated with increased numbers of spumellarian radiolaria; and (5) the earliest Albian Microhedbergella renilaevis “Taxon Range Zone,” defined by the top of Microhedbergella renilaevis. No conclusive Late Aptian microfossil markers were observed above the top of the halite (Ezanga) at Léopard, and the Aptian palynological marker, Exesipollenites tumulus, is not observed (in situ) until within the Ezanga. Organic carbon isotopes through the studied section show a positive excursion in the M. rischi and M. renilaevis zones, which broadly correlates to the OAE-1b set of Oceanic Anoxic Events (Urbino–Paquier–Kilian–Jacob).
