“…The Lower Miocene Chhasra Formation of the Kachchh Basin indicates peak transgression (Biswas, 1993), during which the sea reached distant low-lying areas and the periphery of uplifted highlands. Remains of these sediments are seen between the northern limb of the Jhura (Jhurio) Dome of Kachchh Mainland and the Banni Plain (Fig.…”

A diverse molluscan assemblage dominated by turritellid gastropods found in Kachchh, western India, has been interpreted in the past as Late Jurassic (Oxfordian) in age, based on associated undoubtedly Oxfordian ammonites. Recently, several investigations focused on the assemblage dealing with taxonomic, paleoecological, and evolutionary aspects. An analysis of the associated bivalve fauna, foraminiferal assemblage, and the geological context strongly suggests a Miocene rather than a Jurassic age and invalidates several conclusions drawn from the alleged Jurassic age of the fossils.

“…Structurally, the Banni Basin is described as a half graben (Biswas, 1974, 1987) bounded by the KMF to the south and the Banni Fault (BF) at its northern margin (Figure 1B). The Banni Basin comprises a Precambrian basement overlain by thick Mesozoic and Cenozoic sediments (Biswas, 1993, 2005). A thick pile of ca 250–300 m of Quaternary sediments overlies the Tertiary sediments (Biswas, 1993).…”

A thick pile of ca 250–300 m of Quaternary sediments overlies the Tertiary sediments (Biswas, 1993). The Quaternary sediment thickness is ca 300 m near the southern margin of the KMF, forming an asymmetrical syncline in the subsurface called the Banni Syncline (Biswas, 1993).…”

An uplifted subsurface horst block is present below the region around Bhirandiyala (Biswas, 1993). The present elevations of the Banni Plain and the Great Rann surface is attributed to differential tectonic uplift along subsurface structures, accompanied by seismic activity during the last ca 2 kyr (Biswas, 1974; Maurya et al, 2013, 2016; Merh, 2005; Padmalal et al, 2019; Roy & Merh, 1981).…”

The Depositional Record

Holocene evolutionary history of the Banni Plain in the Great Rann of the Kachchh Basin is reconstructed from a subsurface sediment core of ca 50 m. Detailed data on textural and lithofacies variations, grain‐size analysis, environmental magnetism and accelerator mass spectrometry 14C dates on seven samples were generated on the sediment core retrieved from the Banni Plain near Berada. A high‐resolution record extending back to 10 ka has been reconstructed from the top ca 40 m of the core section comprising shallow marine sediments. The core is divisible into five depositional units. The basal part is a fluvial depositional unit followed upward by estuarine, sub‐tidal, intertidal and supra‐tidal environments. The sediment accumulation rate is highest in the sub‐tidal to intertidal facies (1.9 cm year−1) and decreases towards the supra‐tidal facies to 0.09 cm year−1. Environmental magnetic analysis, χlf coupled with the S‐ratio, indicates high magnetic mineral concentrations during the Early Holocene, suggesting a wet period accompanied by high monsoon precipitation. This is followed by the onset of semi‐arid conditions in the Great Rann of the Kachchh Basin as indicated by the low values of the χlf and S‐ratios. A westward and northward shift in the shoreline towards the deeper part of the basin is suggested during the Late Holocene, which is coupled with aridity and reduced monsoonal conditions. The change in depositional pattern from the retrogradational deposit of fluvial (Unit 1) to estuarine sediment (Unit 2), progressing to sub‐tidal (Unit 3), is attributed to sea‐level transgression followed by regressive intertidal (Unit 4) to supra‐tidal deposition (Unit 5), culminating in complete withdrawal of the sea, aided by tectonic uplift, during the Late Holocene. The results reveal that the sediment accumulation rates and depositional environments changed over time in response to changes in sea level from minima to maxima and then eventually to the present level.
