been dated between Early Triassic to Early Middle Triassic or extend up to Anisian!<br />
Ladinian age. Palaeoclimate during late Late Permian and Triassic time was warm and<br />
semiarid.<br />
Visited GSl, Central Region, and MECL and CMPDI Offices, Nagpur for<br />
discussion and consultation. Besides, visited Tamia, Mutkuli, Jhirpa, Renikhera, Khari,<br />
Dukrikhera, Pipariya (outcrop samples) and Amarwada (bore-cores MPJ-12 & 15) for<br />
collection <strong>of</strong> palynological samples.<br />

Palynological studies <strong>of</strong> sediments from bore-hole GC-17 have revealed presence<br />
<strong>of</strong> palyn<strong>of</strong>lora equivalent to Early Triassic in Chintalpudi sub-basin. Significant<br />
palynomorphs in the assemblage are Falcisporites, Klausipollenites, Chordasporites,<br />
Playjordiaspora. Goubinispora. Nevesisporites, Lundbladispora, Densoisporites.<br />
Classopollis. Rajmahalispora, etc.<br />
Palynostratigraphic studies <strong>of</strong> bore core GJ-6 from Bhopalpalli area were<br />
compiled. Barakar and Raniganj palyn<strong>of</strong>lora have been identified in the above sequence.<br />
Visited Geological Survey <strong>of</strong> India, Calcutta for scientific discussion and<br />
consultation <strong>of</strong> literature. Also visited Kothagudem and Sattupalli areas in Godavari<br />
Graben for collection <strong>of</strong> samples for palynological studies.<br />

Maceral and microlithotype analyses <strong>of</strong> 36 coal pellets representing Manuguru<br />
area have been carried out. The study has revealed that majority <strong>of</strong> the coals are vitric<br />
in nature containing broad microbands <strong>of</strong> vitrinite. Sporangia, seeds, resin bodies and<br />
megaspores are also recorded. The study in fluorescence mode has revealed the existence<br />
<strong>of</strong> fluorescing material in the cell cavities. It indicates that the fluorescing hydrogenrich<br />
matter has occupied the available space present in various macerals.<br />
Visited Yellendu and Manuguru open cast mines <strong>of</strong> Godavari Valley for<br />
collection <strong>of</strong> coal samples for biopetrological study. Also visited Geological Survey <strong>of</strong><br />
India, Calcutta to explore the possibilities for procurement <strong>of</strong> coal samples from various<br />
localities in Wardha-Godavari Valley for organic petrological investigations.<br />
