The history of magnetic minerals during processes of mineralization is however likely complex and few paleomagnetic studies have been applied to hydrothermal systems Townley et al 2007 AlvaValdivia et al 2003 For example paleomagnetism was used to date some old deposits by comparison of the observed paleomagnetic.

Jun 01 20120183321 Introduction Meteorite paleomagnetism is a unique source of information about the ancient magnetic fields in the solar system eg Weiss et al 2010However after the fall of a meteorite on Earth the magnetic carriers of meteorites which are FeNi metallic alloys in most cases start weathering which may hinder the measurement and interpretation of their paleomagnetic record.
