Abstract

About 135 million years before, a form of marine animal called belemnites existed during the geological period of the Jurassic and Cretaceous. The Cauvery Basin is a pericratonic basin that lies along the southeast coast of India. The belemnites fossil used in the present study is collected from Karai East, Ariyalur District, Tamil Nadu. The inner and outer parts of the cross-section differ in the size of calcite forms and building up in the fossil. Geochemical characterization of rostrum and alveolus in the fossil was done to determine the mineral constitutions and assemblages. The elements were characterized by Fourier Transform Infrared (FTIR), Micro Raman, X-ray Powder Diffractometry (XRD) and X-ray fluorescence (XRF) analyses. A strong calcite mineral deposition was observed in the central part of the rostrum together with kaolinite and orthoclase feldspar as minor components. The peak observed in 3421, 2926 and 3436, 2924 cm-1 are the characteristic peaks of kaolinite in the rostrum and the alveolus respectively. The peaks were observed at 1038 cm-1 are the characteristic peak of orthoclase feldspar. The advent methodology directly and non-invasively affords spatially resolved assessments of organic matter preservation and microscale chemical diversity within any geologically preserved terrestrial sedimentary sample in technological applications.
