  • Tasmanian Tertiary Foraminifera
    Papers and Proceedings of the Royal Society of Tasmania, Volume 108 (ms. received 16.3.1973) TASMANIAN TERTIARY FORAMINIFERA Part 1. Textulariina, Miliolina, Nodosariacea by Patrick G. Quilty West Australian Petroleum Pty. Limited, Perth, W.A. (with four plates) ABSTRACT Foraminifera of the Suborders Textulariina and Miliolina and the Superfamily Nodosariacea are recorded from samples of all known Tasmanian marine Oligo-Miocene sections. Thirteen species of agglutinated foraminifera are identified specifically and one category is left in open nomenclature. Thirty species of porcellanous foraminifera (including CrenuZostomina banksi n. gen., n. sp.) are recorded and there are eight open categories. The Nodosariacea is represented by 63 identified species (including Lagena tasmaniae n. sp.) and 10 categories in open nomenclature. Information on each species includes original citation, synonymy of Australian identifications, remarks where necessary and occurrence and age in Tasmania. All identified forms are figured. INTRODUCTION AND ACKNOWLEDGEMENTS The stratigraphy of the Tasmanian Tertiary Marine succession has been reviewed by Quilty (1972). The results noted in that paper are based on foraminiferal studies conducted at the University of Tasmania. Localities, sample numbers etc., mentioned here are detailed further in Quilty (op. cit.) and this paper should be read in company with that paper. This paper is the first of a projected series of three papers documenting the Tasmanian Tertiary foraminifera. Classification adopted in these papers follows closely that proposed by Loeblich and Tappan (1964a) and reviewed by them (1964b) but differs in minor respects which will be indicated where necessary. Quilty (op. cit.) noted that the first record of Tasmanian Tertiary foraminifera was by Goddard and Jensen (1907).

    www.ijcrt.org © 2018 IJCRT | Volume 6, Issue 2 April 2018 | ISSN: 2320-2882 TEXTULARIID AND MILIOLID FORAMINIFERA FROM A 50-CM CORE SEGMENT FROM THE ARABIAN SEA 1Nimmy, P. M., 1*Rajeshwara Rao, N., 1Nandita Nandan, T., 2Neelavannan, K. and 2Hussain, S. M. 1Department of Applied Geology and 2Department of Geology University of Madras, Guindy Campus, Chennai 600 025, India Abstract: The Arabian Sea is one of the most productive regions of the world ocean and hence has been the focus of attention of micropaleontologists from all over the world. A 5.4-m gravity core was retrieved onboard the CRV Sagar Kanya from off Goa, Arabian Sea, and its uppermost 50 cm examined for foraminifers. The systematic paleontology of textulariid and miliolid foraminifera from this core segment is presented with relevant remarks and comments on their ecology and distribution. Keywords: Foraminifera; Taxonomy; Textulariids; Miliolids; Ecology; Arabian Sea. Introduction: The seasonal reversal of the winds caused by the alternate heating and cooling of the Tibet Plateau controls the circulation in the Arabian Sea. It has, therefore, been extensively studied with respect to diverse aspects of both benthic and planktic foraminifers. Between June and September (summer), offshore Ekman transport and intense upwelling along the Oman and Somalia margins (Shi et al., 2000) are caused by the strong south-westerly winds that blow across the Arabian Sea. This upwelling process brings cold, nutrient-rich waters from a few hundred meters depth to the surface and considerably increases the biological productivity in the euphotic zone, making the Arabian Sea one of the most productive regions of the world ocean (Qasim, 1977).

Tel: +90 532 3345893 Received 25 July 2014 E-mail: [email protected] Accepted 28 Sept. 2014 Abstract Cape Town is the second-largest city of the Republic of South Africa. Research is conducted in 3 different stations: Maori Bay, which lies in the southwest of Cape Town, and Pyramid Rock and Partridge Points which lies in the False Bay, southeast part of Cape Town. Samples are taken from young sediments at 10.00 and 20.00 m depths, and collected by scuba-diving method. The aim of the study is to investigate the living benthic foraminifera assemblages in the Atlantic Ocean, and to compare these assemblages with the southeastern part of the Atlantic Ocean, the Arabian Sea, Indian Ocean and Western Pacific assemblages. Moreover, the aim of the study is to determine whether there are any benthic foraminifera forms reaching to the Mediterranean from Pacific Ocean, Indian Ocean or Red Sea via Suez Channel.
