Abstract
Published studies showed micro-tektite level before the Matuyama-Brunhes transition as a glassy object formed by a meteorite impact. The Matuyama-Brunhes transition occurred 781 kyr ago and is the last long-term magnetic reversal.
The motivation of this study was to investigate the potential tektite deposition in ocean sediment from South Atlantic. This is a location where tektites have not yet been found.
