“…The sources of the ages/correlations used in compiling this are listed in the figure title. The available geochronology is at best capable of providing the broad age ranges in which the deposition occurred, often using indirect data eg: ages of intrusives in them or their basement (Pradhan et al, 2012;Kumar et al, 2015) or detrital zircon ages (Malone et al, 2008;Bickford et al, 2011;Amarsinghe et al, 2014;McKenzie et al, 2014;Basu and Bickford, 2015;Joy et al, 2015) to constraint the upper and lower ages of the component Groups from the various basins. Direct dating of the sediments and associated rocks (eg: Zachariah et al, 1999;Conrad et al, 2011;Gopalan et al, 2013;Tripathi and Singh, 2015) is sparse.…”
