“…The larger of these two terraces, denoted by Yatheesh et al (2006) as 'Terrace off Trivandrum (TOT)', lies approximately south of the latitude of Trivandrum (Fig. 2) and a smaller terrace, referred as 'Alleppey Platform' (Singh et al, 1999) or 'Terrace off Quilon' (Rao and Bhattacharya, 1975), lies approximately between latitudes of Alleppey and Quilon. For ease of further discussion in this study, we will refer that smaller northerly terrace as 'Alleppey Terrace' (AT) and the larger southerly terrace as 'Trivandrum Terrace (TT)', and the whole region comprising those two terraces as 'AlleppeyeTrivandrum Terrace Complex (ATTC)'.…”

“…However, during the late Miocene the Western Indian margin experienced a heavy influx of terrigeneous clastic sediments (Singh et al, 1999). This phase of high sedimentation is associated with fracturing, shear zone movements, downfaulting and collapse of several parts of the shelf, and may be attributed to a change in the tectonic regime following the Himalayan collision (Ghosh & Zutshi, 1989).…”

Total sediment thickness is based on the isopach maps of Rao and Srivastava (1984) and Rao et al (2002).…”

Sedimentation record in the Konkan–Kerala Basin: implications for the evolution of the Western Ghats and the Western Indian passive margin

The Konkan and Kerala Basins constitute a major depocentre for sediment from the onshore hinterland of Western India and as such provide a valuable record of the timing and magnitude of Cenozoic denudation along the continental margin. This paper presents an analysis of sedimentation in the Konkan-Kerala basin, coupled with a mass balance study, and numerical modelling of flexural responses to onshore denudational unloading and offshore sediment loading in order to test competing conceptual models for the development of high-elevation passive margins. The Konkan-Kerala basin contains an estimated 109,000 km 3 of Cenozoic clastic sediment, a volume difficult to reconcile with the denudation of a downwarped rift flank onshore, and more consistent with denudation of an elevated rift flank. We infer from modelling of the isostatic response of the lithosphere to sediment loading offshore and denudation onshore infer that flexure is an important component in the development of the Western Indian Margin. There is evidence for two major pulses in sedimentation: an early phase in the Palaeocene, and a second beginning in the Pliocene. The Palaeocene increase in sedimentation can be interpreted in terms of a denudational response to the rifting between India and the Seychelles, whereas the mechanism responsible for the Pleistocene pulse is more enigmatic.

“…Sediment thickness varies from 1-3 km in the southern WCMI and k/creases to more than 6 km in the north (Singh et al, 1999). The presence of the Bombay High structure, a potential oil bearing structure together with other oil and gas bearing structures are indicators for the hydrocarbon potential of the WCMI.…”

Abstract.Geothermal these aspects, the scope for the generation of methane and formation of gas hydrates along this margin is favorable.These conditions formed the basis for both Single Channel Seismic (SCS) and Multi Channel Seismic (MCS) studies to identify gas hydrate occurrences along the WCMI, through the presence of BSRs (Fig. 1).Evolution of the continental margin can be better understood from the knowledge of its geothermal structure. Heat flow estimates made from BSR depths are significant from the areas that are inaccessible and probe measurements are risky. BSR-derived heat flow values gives knowledge of 1) Geothermal structure and heat flow distribution trends along the margin 2) Regional/local scale heat flow variations which decipher the prevailing fluid expulsion processes, sediment thickening and the nature of heat transport mechanisms i.e. whether advective/conductive along the
