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 />

A draft manuscript "Clavadiporopol!enites raneriensis gen. et sp. novo from the<br />

Tertiary sediments <strong>of</strong> Bikaner District, Rajasthan, India" was prepared.<br />

Programme 3.12<br />

Objective<br />

Krishna Anlbwani & R.S. Singh<br />

Palynostratigraphic investigations <strong>of</strong> the Tertiary sediments<br />

<strong>of</strong> Eastern Coast <strong>of</strong> South India<br />

To study palyn<strong>of</strong>lora recovered from selected sections and to<br />

recognise their ecological importance<br />

To establish biozones, correlation and dating <strong>of</strong> sediments<br />
