The magnetic stratigraphly of seven cores of deep-sea sediment established the existence of a short interval of reversed polarity in the upper part of the Brunches 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.
七份深海沉积物岩芯的磁性地层学研究确立了布容正向极性时期上部一个短的反转极性段的存在。岩芯中的反转带与古生物学边界很好地相关，被命名为布莱克事件。其边界估计在 108000 到 114000 年前，误差幅度为正负 10%。
