Petrology of Panandhro Lignite Deposit, Gujarat in Relation to Palaeodepositional Condition

Petrological investigations on Early Eocene lignite from two mine sections of Block-1 in Panandhro Lignite field, under both normal incident (white) and fluorescence (blue light excitation) modes, reveal that deposit is rich in maceral huminite content with sub-Ordinate amount of liptinite and low inertinite contents. The maceral composition indicates that sub-Bituminous C lignites in both the mine sections are more or less similar with minor differences. Gelification and Tissue Preservation Indices suggest the deposition of lignite in lower delta plain environment in lagoonal conditions.
