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 />
