Magnetic signatures of the Almahata Sitta meteorites
IFG/ Univ. Tuebingen, Fac. Geosciences, Univ. Muenchen, Germany
We will present first results of our pilot study on the magnetic
signature and paleomagnetic record of Almahata Sitta polymict ureilite.
A large set of magnetic properties has been studied, also at low and
high temperatures, in order to determine the magnetic phase composition.
The paleomagnetic record of Almahata Sitta is of extraterrestrial
origin, most probably from the Ureilite parent body.
Additionally, SEM/EDX, EMPA and optical microscopy provided a more
detailed view of the magneto-mineralogy/petrology and fabric of this
Our results will be compared with magnetic data of some other ureilites.
