Through analysis of seafloor magnetic anomalies and dating of reversal sequences.
Paleomagnetic and Archaeomagnetic Dating - Mac OS X Server Geomagnetic reversal - Wikipedia, the free encyclopedia Authors: Speranza, F. Different igneous and sedimentary rocks are rich in.
magnetisation in archaeological materials is called archaeomagnetic dating.
) stored palaeomagnetic data from archeological materials and lavas alone; however, paleomagnetic, rock magnetic, and chronological data from sediments deposited over the past 50 ka have broad applications across the geosciences.
These include understanding past changes in the geomagnetic field, physical environments, climate, and anthropogenic impact. ), the latest modifications to the general structure of the GEOMAGIA50 database and more specific changes to the archeo/volcanic database are described.
