- Аннотация: On the Atlantic coast of the USA, spanning more than 1000 km from Florida to NewJersey, there are over 500,000 oval craters, called "Carolina Bays". Samples extracted with a Nd magnet from loose sediments of 3 craters, located 10 km north of Myrtle Beach, South Carolina, were studied at the Geophysical Observatory "Borok" IPE RAS with SEM "Tescan Vega II". Micro- and nanoparticles and films of pure Ni were found on the surface of the rounded ilmenite, magnetine and quartz grains, as well as microparticles of native metals and alloys. For the first time in the material of these craters, we found the traces of the process of thermal interaction of terrestrial and cosmic materials that occurred in situ. It is assumed that the craters were formed by numerous fragments of an aerodynamically destroyed cosmic body (a comet or an asteroid), approaching the Earth on a very oblique trajectory.
