During the Early Maastrichtian, the Indian plate was positioned further south at mid-latitudes (~30°S) relative to its present position in the northern hemisphere. The tropical to sub-tropical climate favoured the formation of coal and limestone, and the higher concentrations of greenhouse gases led to enhanced terrestrial productivity 27 .

Petrographically, Maastrichtian limestones were classified as pack stone/grain stone facies with wackestone and mudstone facies. The ferruginous limestone litho-unit are rich in ferruginous materials with algal remains and bryozoans (Fig. 3 d, e). The rich iron content in these limestones indicates shallow and high energy conditions.
