Abstract

One key to address the issue of the location of the K/Pg boundary at the Um Sohryngkew sections to look at C carb , C org , Hg/TOC, Mo/Al chemostratigraphies, alongside Hg isotopes, in previous studied K/Pg sections in the Meghalaya area, and compare them with same type of data reported in Sial et al. (2016). The possibility of diachronic deposition cannot be totally discarded, and the K/Pg boundary could have been recorded in the Langpar Formation at one site and in the contact between the Mahadeo and Langpar formations in another. A tectonic-induced doubling of the sequence is also possible as the Meghalaya area, within the Shillong plateau, has been linked to a number of kinematic changes, including pop-up tectonics, since the Cretaceous.
