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.
