Abstract

The Wagad Uplift is a region in the eastern part of the Kachchh Basin of western India which exposes Middle to Upper Jurassic sedimentary rocks. The more than 520 m thick succession is dominated by third-order cycles with highstand systems tracts being composed of coarsening-upwards parasequences. The Callovian to Lower Oxfordian succession is dominated by asymmetric couplets of comparatively thick highstand systems tracts and thinner transgressive systems tracts reflecti g a general sea-level rise. The Middle-Upper Oxfordian Kanthkot Ammonite Beds are characterized by condensed, fossiliferous, bioturbated, poorly sorted silt- to sandstones and represent deposits of the maximum fooding zone. While sediment starvation continued in the westernmost Wagad Uplift until mid-Kimmeridgian times, a delta complex prograded into the basin from the east. These strata reflec the flling and continuous shallowing of the basin towards the end of the Jurassic. The sedimentary unit is characterized by stacks of highly asymmetric transgressive-regressive cycles, the transgressive part being represented only by thin lag deposits. Seven facies could be distinguished in the Jurassic sedimentary succession, which refect different energy conditions, water depths, and sedimentation rates.
