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 />

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 />
