1. Title of the Project:

Neoproterozoic cratonic basins in southern India: Palaeoclimatic, palaeoenvironmental and
palaeotectonic implications

2. Name of Proposing Scientists:
Sarbani Patranabis-Deb
3. Brief objectives and justification:
The objective of the present study has been defined on the basis of several stratigraphic
questions, as well as on the basis of observations during my last ten years research work which
explores stratigraphy and sedimentology of the Purana successions of peninsular India.

The focus of the present research is on the stratigraphic basin analysis. The aim is on
sedimentology and sequence stratigraphy and their application to palaeogeography,
palaeooceanography and palaeoclimatology of the Neoproterozoic basins of the Dharwar
craton, peninsular India.

• To continue with the facies analysis of the siliciclastics and the carbonates in four
basins namely Kurnool, Badami, Bhima and Sullavai of Dharwar craton to determine
the paleo-depositional environments and to determine the tectonic controls on the
basin evolution. The facies analysis would be geared to identify different facies belt,
and the history of sea-level fluctuations, sedimentology and the sequence stratigraphy
to achieve complete basin analysis.
• Extensive development of black limestone in the Kurnool and Bhima successions may
be related to maximum flooding event (Patranabis-Deb 2001) and may be used for
correlation of the isolated basins in south Indian craton.
• Dating of a few key lithologic elements from all the above-mentioned basins to
constrain the stratigraphy on collaborative basis with University of Johannesburg.
• The lithofacies analysis will be combined with geochemical analysis of the carbonates
to realize chemostratigraphic correlation between the carbonate successions in
different outcrop belts in all the basins of peninsular India. The chemostratigraphic
correlation on a regional scale may be used to overcome the lack of precise
biostratigraphic controls.
• Combining geochemical, geochronological data with the facies analysis, and
palaeomagnetic study, which is already being initiated, an attempt will be made to
reconstruct the tectonic and paleoclimatic condition.
