Biostratigraphic Aspects and Depositional Environments of Eocene Deposits of ... Nummulites gallensis (HEIM), Nummulites lehn eri SCHAUB, Nummulites uranensis (de la HARPE). The indication that pelagic and turbidite facies are Depending on local hydrodynamic conditions, autochthonous Nummulites deposits can be preserved as in situ winnowed bioaccumulations or be accumulated offshore, onshore or … depositional environments were developed in grabens, ramps, and footslopes of the down-faulted Middle Eocene blocks, i.e., syn-tectonic deposition. This peculiar hydrodynamic behaviour of Nummulites could explain the diversity of depositional models. In the Chor Gali Formation chief mode of sedimentation of the Early Eocene Chor abundance of small lenticular Nummulites associated with Gali Formation. in foraminifera) is an indication of the deposition of this facies in the depth of open sea [9]. The fluviatile Oligocene sediments were highly controlled by the structural and topographic lows, where a substantial thickness was deposited, Gebel Ahmer Existence of benthonic bioclasts such as milliolide and nummulite family in calciturbidite facies (B1 to B5) indicates deposition in a platform environment. Variations in nummulite morphology (size and shape) were used to distinguish a number of subfacies which correspond to different depositional environments. The Nummulites laevig atus Range Zone has been recognized in the Sirikli Hill section in the study (Fig. 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. Formation, the vertical and lateral faunal changes and depositional ... a shallow marine environment, implying almost similar depositional conditions for the whole sequence of the Çayraz Formation (Ünalan ... Nummulites-Assilina packstone and orthophragminid-nummulitid na sp．，Discocyclina sp．，Idalina sp．，Nummulites sp．， Nummulites globulus，Perloculina sp．，and Quiquelo-culina sp． The interval largely consists of limestone and marl． Age:middle Eocene 4 Depositional environment and mi-crofacies Sedimentological and paleontological studies show that a ramp type carbonate platform sedimentary Nummulites associated along with Alveolina sp. Six depositional facies have been identified in the El Garia Formation, ranging from high-energy nummulitic grainstones to laterally-equivalent lower-energy nummulithoclastic accumulations. with Assilinas were assigned either deep or shallow water Depositional Settings: The shallow shelf facies was the shelf environments. Six depositional facies have been identified in the El Garia Formation, ranging from high‐energy nummulitic grainstones to laterally‐equivalent lower‐energy nummulithoclastic accumulations.
