Abstract

Elemental composition of two groups of 12 clay samples, at and above the Cretaceous/Paleogene (K/Pg) boundary at Byala (Black Sea shore, Eastern Bulgaria), is studied by Neutron Activation Analysis (NAA) in order to trace impact events. Iridium anomaly and a certain set of trace elements, together with biostratigraphic data, point to two possible impact events recorded: the first one (at the K/Pg boundary), linked to the giant Chicxulub impact in Mexico; and a second one (above the K/Pg boundary), possibly linked to the later in age, smaller and closer in distance, Boltysh impact in Ukraine.
