The palynoassemblage <strong>of</strong> Rajpardi lignite, Tarkeshwar Formation (Early Eocene)<br />
consists <strong>of</strong>angiospermous pollen, pteridophytic spores and fungal fruiting bodies. The quantitative<br />
and qualitative analyse's <strong>of</strong> the palynoassemblage have been done and illustrated<br />
through histograms. It is observed that the angiosperm pollen especially palms are dominant<br />
in the assemblage, followed by the pollen <strong>of</strong> Alangiaceae, Bombacaceae and Linaceae.<br />
A majority <strong>of</strong> taxa are similar with the paJynoassemblage <strong>of</strong> Naredi Formation (Early<br />
Eocene) <strong>of</strong> Kutch, as Lakiapol/is ovatus Cenozone is recognised in both the assemblages.<br />
But Rajpardi palyn<strong>of</strong>lora shows comparatively a large number <strong>of</strong> fossil Alangium grains.<br />
Most <strong>of</strong> angiospennic pollen are similar to modem taxa. The habitat <strong>of</strong> fossil palynotaxa is<br />
interpreted on the basis <strong>of</strong> comparison with habitat <strong>of</strong> similar extant plants.<br />

150 samples were collected from Okha, Metapur, Shivarajpur and adjacent areas<br />
<strong>of</strong> South Saurashtra, Jarnnagar District, Oujarat for palynological studies.<br />

Programme 3.11<br />
Objective<br />
Palynological investigation <strong>of</strong> the Tertiary formations <strong>of</strong><br />
Rajasthan (other than Kapurdi area)<br />
To build up the palynostratigraphy <strong>of</strong> different Tertiary formations<br />
1b correlate different Tertiary formations <strong>of</strong> Rajasthan with<br />
those in Gujarat<br />
To infer the palaeoecological condition <strong>of</strong> deposition<br />
Two bore-holes Kl4 and Kl6 drilled by OSI at Kuchaur-Benia area, Bikaner District<br />
were palynologically investigated. The assemblage comprises Piladiporocolpites,<br />
Psiladiporocolpites and Retidiporocolpites <strong>of</strong> Diporocolpis apertural type. Besides,<br />
Ocimumpol!enites - fossil pollen resembling the extant pollen <strong>of</strong>Ocimum (Lamiaceae) was<br />
also identified. Pluricolumel!atepol/is, another hexacolpate pollen, is also conunon in the<br />
assemblage.<br />
