Cryptochrons
WebThe magnetostratigraphy from Ocean Drilling Program (ODP) Site 1095, off the Pacific margin of the Antarctic Peninsula, contains an extra normal polarity event that occurs near the base of Chron 4r.2r (8.072-8.699 Ma), which we interpret to be cryptochron C4r.2r-1. Owing to the relatively high sedimentation rates (about 90 m/m.y.), this event is … WebThese chrons fall in the 22 m thick Scaglia cinerea part of the Massicore. This formation has a simple magnetic mineralogy dominated by magnetite and is suitable for paleointensity investigations. Magnetic susceptibility is rather uniform within the formation and is determined by paramagnetic minerals.
