Abstracts

The platinum-group elements comprise a very small percentage of elements in the earth’s crust. The primary sources of them are meteorite impacts and volcanism. The study of PGEs anomaly in sediment profiles as a possible indicator of impact began in 1980, when was suggested a link between high levels of iridium and the mass extinction event in Late Cretaceous.
