Lignite samples from three bore-holes (NLE-27, 35 and 36) <strong>of</strong> the Neyveli lignite<br />

field have been assessed quantitatively under fluorescence mode (blue light excitation) to<br />

generate the required data on fluorescing and non-fluorescing macerals for comparative<br />

study. TIle studies indicate that the macerals <strong>of</strong> the huminite group are dominant followed<br />

by Iiplinite and inertinite.<br />

Palynostratigraphy <strong>of</strong> the Tertiary sediments nf Gujarat<br />

Objective<br />

To correlate Tertiary formations<br />

and adjacent areas<br />

To decipher the palaeoecological<br />

<strong>of</strong> Kutch with those in Broach<br />

condition <strong>of</strong> deposition<br />

To compare the fossil pollen with the living ones<br />

Palynoassemblage recovered from Matanomadh Formation is rich in angiosperm<br />

pollen. The assemblage contains 21 genera and 28 species. Dandotiaspora dilata occurs in<br />

good number. The recovered assemblage is different from the assemblage in a Nala section<br />

near Matanomadh Village. The latter assemblage is dominated by Trilatiporites, Lakiapollis,<br />

Meliapollis and Neocouperipollis, indicating an Early Eocene age.<br />

Palyn<strong>of</strong>ossilS recovered from the samples <strong>of</strong> Rajpardi lignite, Broach District show<br />

the abundance <strong>of</strong> angiosperm pollen, especially the tricolporate and tetl'acolporate assigned<br />

to family Alangiaceae, followed by monocotyledonous pollen <strong>of</strong> Palmae. The other pollen<br />

assignable to family Bombacaceae, Labiatae, Anonaceae, etc. and fungal fruiting bodies <strong>of</strong><br />

Microthyraceae arc also common in the palynoassemblage. It is concluded that warm and<br />

humid tropical climate was prevalent during the time <strong>of</strong> deposition.<br />

Palynological investigation <strong>of</strong> the Tertiary formations <strong>of</strong><br />

Rajasthan (other than Kapurdi area)<br />

Objective<br />

<strong>of</strong> dijJerelll Tertiary forma­<br />

To build up the palynostratigraphy<br />

tions<br />

To correlate different Tertiary formations <strong>of</strong> Rajasthan with<br />

those in Gujarat<br />

To infer the palaeoecological<br />

condition <strong>of</strong> deposition<br />
