Abstract: Sole marks in storm event beds are described for the first time from Talchir Formation (Permo-Carboniferous) of Raniganj Basin, India. Gutters and grooves trending subparallel to wave ripple crests were formed by shore-parallel geostrophic flow at the initial phase of storms. During intensification of storms, oscillation- dominated shore-normal current produced gutters, grooves and bipolar- bimodal prod marks and bounce marks at nearly perpendicular or highly oblique to the axis of major wave ripple crests. Superposition of shore-normal oscillatory flow on shore-parallel geostrophic current during peak storms is evident from curvilinear, crosscutting and turnabout groove marks. Hydrodynamic interpretation of these sole marks, interrelationship between palaeogeographic constraints governing the overall sediment dispersal pattern, and the stratification architecture in storm event beds signify complex interplay of mutually perpendicular shore-parallel and shore-normal components of storm current in shallow marine setting. © 2004 Elsevier B.V.
