Conclusions
[34] With the aid of thermomagnetic analysis up to 800oC we revealed the detailed pattern of
how metallic iron particles are distributed in space and time, which
is impossible to detect with "direct methods''. Our main discovery
is the synchronous enrichment by iron particles in Miocene sediments
of the Khalats and Kvirinaki sections that are more than 1500 km
apart. This phenomenon that occurred 12.6-12.2 Ma, is most likely
to be global and space-connected. It does not depend upon local
deposition, sediment composition, redox conditions, etc. Long
duration of this phenomenon and its global scale cannot have
resulted from a single impact event.
