Abstract
The magnetic stratigraphy of seven cores of deep-sea sediment established the existence of a short interval of reversed polarity in the upper part of the Brunhes epoch of normal polarity. The reversed zone in the cores correlates well with paleontological boundaries and is named the Blake event. Its boundaries are estimated to be 108,000 and 114,000 years ago ± 10 percent.Keywords
