With the aid of thermomagnetic analysis up to 800o C we studied the detailed pattern of how native iron is distributed in Miocene sediments of two sections, Khalats Turkmenia and Kvirinaki Georgia, which are more than 1500nbsp;km apart. Out main result is that enrichment by native iron particles was synchronous in both sections. This phenomenon is of extraterrestrial origin and does not depend upon local conditions of deposition. The length of iron-enriched interval from 12.6 to 12.2nbsp;Ma over a vast area cannot result from a single impact event.
