Tóm tắt

Micro and macrofossil assemblage have been recovered and documented from the lignite beds of the Vastan lignite mines, Cambay Basin, Gujarat. These are extracted after dissolving amber pieces inclusive of pollen spores, epiphyllous fruiting fungal bodies, algal elements, insect fossils with some unidentified biotic groups. Of these, the major dominant flora belongs to angiosperm origin, in accompaniment to pteridophyte spores and fungal elements. Recorded palynotaxa viz. Proxapertites, Spinizonocolpites, Neocouperipollis and Acanthotricolpites are significant elements for tropical humid vegetation. Rich terrestrial amber palynomorphs and palynodebris suggest proximity source vegetation. Characteristic biotic interactions within the dense evergreen tropical rain forest environment is suggestive of mutual association among groups during the Early Eocene and share close affinities with those of Kutch and Barmer, Bikaner and Nagaur basins.
