Abstract

Damodar basin displays an excellent development of Lower Gondwana sediments in isolated depressions in an East-West trending narrow linear belt with southerly basin slope. In this paper, integrated modelling carried out for the eastern-most depression viz., Durgapur Depression has been illustrated. Mainly the application of a priori knowledge of the basin for carrying out modelling has been discussed. Adequate characterisation of the subsurface geologic structure using different data individually is prone to errors. Inherent problems of sills/ dykes and the complexities due to presence of many coal seams necessitate integrated modelling of Durgapur Depression. This prompted us to construct a detailed geological model integrating various sets of data.
