Gauss-Matuyama reversal

Gauss-Matuyama reversal

The Gauss-Matuyama Reversal was a geologic event approximately 2.588 million years ago when the Earth's magnetic field underwent reversal.

This event, which separates the Piacenzian from the Gelasian and marks the start of the Quaternary [http://www.inqua.tcd.ie/documents/QP%2016-1.pdf Clague, John "et al." (2006) "Open Letter by INQUA Executive Committee" "Quaternary Perspective, the INQUA Newsletter" International Union for Quaternary Research 16(1):] ] , is useful in dating sediments.

Biological effects

The event is marked by the extinction of calcareous nannofossils "Discoaster pentaradiatus" and "D. surculus", among others.
