Abstract
Aspects and examples of chemical remagnetization are dealt with. This type of remagnetization is likely to be a significant one in rocks laid down in low palaeolatitudes but may also be of general importance in intrusives, accompanying for instance post-emplacement hydrothermal alterations. There may be no significant stability difference between primary and secondary components and consequently the net magnetizations, which may define strongly deviating directions, may easily be wrongly considered as palaeomagnetic directions. In particular, the late Palaeozoic palaeomagnetism for Europe is discussed in some detail suggesting that fundamental problems associated with the magnetization of the rocks considered have been overlooked.
