Dating stalagmite usi
ng paleomagnetic methods is still
in its early stage of development.
Questions still remain regarding
the nature and origin of the magnetic carriers and the
reliability of the natural remanent magnetization preserved within the thin carbonat
ed
laminations of stalagmites. Here we apply high
-
resolution rock
-
and paleo
-
magnetic
methods
on two (altered and preserved) stalagmites in order to identify the magnetic
and mineralogical signatures and to
assess
the stability of the remanence.
