The first find of native platinum in the transitional clay layer at the cretaceous/paleogene boundary in the gams section (Eastern Alps, Austria)

As a result of detailed studies by the method of microprobe analysis, a particle of natural rhenium was found for the first time in the transitional clay layer at the Cretaceous-Paleogene boundary in the Gams section (Eastern Alps). It is concluded that the formation of natural rhenium was related to a volcanic aerosol that arose due to the magmatic activity of a mantle plume 65 Myr ago.
