Microfossil Analysis of Neyveli Lignite by Polished Surface Technique

Abstract

Microscopic examination of the polished surface lignite blocks has revealed well preserved microfossils. Different types of dispersed plant tissues such as parenchyma, sclerenchyma, fibres, vessels and cork cells have been recognized apart from spores and pollen, fungal remains and woody structures. The microconstitution of the lignite indicates peaty, woody, lignitic or brown coaly layers suggesting heterogeneous formation of the lignite deposit.
