APPLICATION OF SEDBA TO SEDIMENTOLOGY: DEFICIENCIES OF INFORMATION AND NEED OF VERTICAL PROFILES OF LITHOLOGY AND SEQUENCES OF SEDIMENTARY STRUCTURES

Project IGCP-269-SEDBA,a Global Database in Sedimentary Petrology is a wonderful in-ternational project that would be of immense value to sedimentology. While examining the database critically it was observed that there are some deficiencies of information in SEDBA and need rectification. Deficiencies are regarding(1)insufficient space for information,(2)ambiguity in information,(3)improper arrangement of information,(4)lack of further subdivision of infor-mation and(5)irreevant and unnecessary information. Secondly,SEDBA is restricted to sedi-mentary petrology only. To apply SEDBA to sedimentology some modifications are essential to make it more useful and meaningful. These modifications may be regarding inclusion of(1)litho-logical and Lithofacies maps,(2)diagrams and figures showing stages of tectono-sedimentary evoloution of the basin,(3)maps and diagrams showing basin configuration,(4)provision for vertical profiles of lithology and lithologs,(5)sequences of sedimentary structures,(6)geological cross-sections of the area and(7)other important figures and photographs.
