The presence of planktonic foraminifera and radiolarians suggests an outer ramp to basin setting comparable to the depositional setting of Flugel's (2004) RMF5 and Wilson's (1975) SMF-3 (Fig. This suggests a portion of foraminifera from the active channel site have been transported from the northern Bay of Bengal. The Lockhart Limestone is 50 meters thick in the Potwar Sub-basin and 85 meters thick in the Hazara Sub-basin. environments of deposition have been inferred on the bases of the occurrence of environmentally restricted benthic foraminifera taxa, some which belong to the following generaQuinqueloculina, Hopkinsina, Spiroplectamina, Lenticulina, Heterolepa, Alveolophragmium and Textularia. Similarly, several workers9-14 have studied the foraminiferal ecology and its environment along the east coast of India. Based on these evidences an outer ramp setting is suggested for this microfacies while dolomite is formed during secondary diagenetic process. Friedman,V. ​A full account of 67 ditch cutting samples collected from Well 5, OML 34 in the Niger Delta at depth intervals between 2441m to 3650m is presented. An example of autocyclic sedimentation on a carbonate platform was provided by Septfontaine M. (1985): Depositional environments and associated foraminifera (lituolids) in the middle liasic carbonate platform of Morocco.- Based on depositional geometries, biogenic contents and lateral and vertical variations of facies, three depositional models are proposed to illustrate the evolution of the Asmari carbonate platform. During the Chattian, large benthic foraminifera and coral-coralline red algae were dominant, while throughthe Early A total number of 35 samples were collected from a 30 m thick quarry section and used to prepare 35 thin sections. 0000001369 00000 n Masters Thesis, University of Texas at Dallas. The study area is a tectonized mountainous region with … They construct their tests by gluing sedimentary grains together, in contrast to the other types of foraminifera, which secrete their tests. All larger benthic foraminifera (LBF) are marine and neritic and live in oligotrophic reef and carbonate shoal environments (BouDagher-Fadel, 2008). 0000005023 00000 n Foraminifera (single-celled protists) have a long geological record. Quinault Foraminifera, therefore, reflect varied depositional environments. Depositional Environments – Sandstone . Benthic foraminifera are known to be sensitive to changes in organic carbon content in the sediments, and changes in their assemblage composition therefore reflect synchronous variations in the quantity and quality of carbon reaching the seafloor. In addition, we can analyze the geochemistryof their calcium carbonate shells, which provide a variety of proxies depositional carbon loss. interpretations for both formations using benthic foraminifera in combination with lithological association, sedimentary structures and early diagenetic features. Larger foraminifera represented by the porcellaneous imperforate tests such as Archaias and Peneroplis may point to the depositional environment being within the photic zone in tropical carbonate platforms and slightly hypersaline [17, 35, 37, 54].
