- Abstract
Sequence of strata with consistent and monotonous repetition of two or more kind alternating lithologies are quite common in geological record through the ages and are interpreted as a product of cyclic sedimentation. Cyclic depositional pattern is extensively found in fluvial deposits. Here a brief model of regional depositional stacking pattern is proposed based on the observations from regional geophysical log correlation as well as core based interpretation from Karanpura field. Subsurface facies study from this marginal Gondwana basin enhanced the understanding of stacking pattern and depositional cyclicity preserved in middle Permian Barakar Formation. Four major fining upward depositional cycles have been established regionally, each consisting of low and high accommodation system tracts at bottom and top of individual cycle respectively. Findings have been correlated with basin evolution process and major geological time events.
