The succession of varying facies tracts filling within a canyon, or a deep incised gully, cutting across the delta-front lobes at the shelf-edge requires to be explained by high-frequency allocyclic and/or autocyclic events. A ‘fifth- and sixth-order’ sequence-stratigraphic model for the shelf-edge canyon-fill or gully-fill is here proposed for the...

Ichnology has widely been used in paleoecological, paleoenvironmental, and evolutionary analysis. Rosselia is a dwelling burrow of infaunal, detritus-feeding terebellid polychaetes and is common in Phanerozoic shallow-marine deposits. The crowded Rosselia ichnofabric (CRI, i.e., a dense occurrence of Rosselia) provides itself in this study as a val...
Article
The Glossifungites ichnofacies can be a signature of allogenic processes that demark omission, exhumation, and ravinement or indicate autogenic processes impacting several depositional scenarios, such as incised valleys, submarine gullies and canyons, erosive shoreface, tidal channels, and dewatered muddy substrates. Comparatively, autogenic surfac...
Conference Paper
Post-burial deformation of unconsolidated sediments leads to the development of distinctive sedimentary structures called the soft-sediment deformation structures (SSDS). The sand volcanoes and their associated array of faults can truly exemplify the SSDS, which particularly indicate the paleo-earthquake activities if found along a lithostratigraph...

Project
Process-ichnology provides the physicochemical conditions of sedimentation, substrate rheology, ecological stress factors, inter-taxa interactions, and the intensity of erosional exhumation, inundation, pedogenesis, and non-deposition that a sedimentary substrate can potentially experience. The existing sedimentological and stratigraphic context of the Cenozoic succession of the Kutch Basin is incomplete without integrating the process-ichnological information with the existing sedimentological and palaeontological data into a high-frequency auto- and allo-stratigraphic framework. The proposed project aims (1) to analyse the ichnological parameters, (2) to estimate the substrate-conditions and ichno-rheology of the major sequence stratigraphic surfaces, (3) to evaluate the specific palaeobiological processes involved in bioturbation and bioerosion, and (4) to construct a comprehensive and integrated depositional, process-ichnological, and stratigraphic model as a global analogue for the mixed carbonate-siliciclastic marginal-marine and continental system.
Project
Using onshore and offshore seismic and well data combined with outcrop studies in Paleogene litho-units a holistic approach targeted in Kutch basin which will bring out a stratigraphic template in the basin.
