Six depositional facies have been identified in the El Garia Formation, ranging from high-energy nummulitic grainstones to laterally-equivalent lower-energy nummulithoclastic accumulations. The Nummulites laevig atus Range Zone has been recognized in the Sirikli Hill section in the study (Fig. in foraminifera) is an indication of the deposition of this facies in the depth of open sea [9]. The Eocene Nummulite carbonates (Central Tunisia and NE Libya): Sedimentology, depositional environments, and application to oil reservoirs Existence of benthonic bioclasts such as milliolide and nummulite family in calciturbidite facies (B1 to B5) indicates deposition in a platform environment. Interpretation of Depositional Environment: The abundance of platform-top carbonate clasts and shallow benthonic foraminiferal taxa (miliolids and discorbids), often associated with sea grass meadows (e.g. Biostratigraphic Aspects and Depositional Environments of Eocene Deposits of ... Nummulites gallensis (HEIM), Nummulites lehn eri SCHAUB, Nummulites uranensis (de la HARPE). In the Chor Gali Formation chief mode of sedimentation of the Early Eocene Chor abundance of small lenticular Nummulites associated with Gali Formation. This peculiar hydrodynamic behaviour of Nummulites could explain the diversity of depositional models. Variations in nummulite morphology (size and shape) were used to distinguish a number of subfacies which correspond to different depositional environments. 3). Sequence stratigraphy and depositional environment of the Oligocene deposits at Firozabad section, southwest of Iran based on microfacies analysis ... Nummulites fichteli intermedius-group, Nummulites vascus- incrassatus group, Operculina complanata, Heterostegina spp., Neorotalia viennoti globigerinids. Six depositional facies have been identified in the El Garia Formation, ranging from high‐energy nummulitic grainstones to laterally‐equivalent lower‐energy nummulithoclastic accumulations.
