Programme 8.3 Potassium-Argon dating <strong>of</strong> sedimentary and igneous<br />

rocks<br />

Ohjective To date the glauconitic sandstone collected./i"om Vindhyan deposits<br />

in UP and Rajasthan<br />

PROJECT 9<br />

Programme 9.1<br />

Ohjective<br />

To date the Deccan Trap samples and .\)'nthesize the data with<br />

jfJssil studies in eollahoration with Cenophytic Department<br />

To develop data acquisition and reduction .\ystem<br />

11,e high voltage circuit in the MS control unit was checked and by substituting<br />

some components, voltage was increased enabling scanning <strong>of</strong> lower masses. The flame<br />

photometer was modified to get digital read out's for various potassium concentration. An<br />

UPS system was installed and tested. Glauconite was separated from some Vindhyan<br />

sandstone samples. The gettering perfonnance <strong>of</strong> the extraction, purification system was<br />

also checked by recording residual gas spectra.<br />

Data bank for Palaeozoic-Mesozoic palynology, using expert<br />

system and compilation <strong>of</strong> catalogues, atlases and<br />

other palynological information<br />

To index and update new data into the existing data hanks<br />

To develop data-hase jfJr distrihution <strong>of</strong> stratigraphically important<br />

taxa<br />

To estahlish data-hase for identification and retrieval <strong>of</strong><br />

palynotaxa<br />

Updating <strong>of</strong> databank on palynology <strong>of</strong> Indian Gondwana sediments and related<br />

aspects was continued. Editing <strong>of</strong> already stored data was also done to get the unifomlity in<br />

the style <strong>of</strong> data stored for testing the search retrieval programme.<br />

Department <strong>of</strong> PGGP : Group Effort<br />

The search retrieval programme developed at the <strong>Institute</strong> was finalized and tested.<br />

The programme is named "DCB" after Late Dr D.C. Bharadwaj, Ex-Deputy Director at this<br />

<strong>Institute</strong> who initiated cataloguing <strong>of</strong> references and planned to have database on computer.<br />
