Title: Paleomagnetic study of the Kaba meteorite
Authors: Gattacceca, J.; Gounelle, M.; Lima, E. A.; Weiss, B. P.

Kaba is the least thermally metamorphosed of all carbonaceous chondrites of the CV group, and shows no petrologic evidence for shock, making it a good candidate as a recorder of magnetic fields in the early solar system. Kaba belongs to the oxidized CVB sub-group, and contains abundant magnetite. This magnetite was formed by aqueous alteration on the parent body about 8 Myr after the formation of the solar system. This age is at the boundary when external magnetic field sources of nebular or solar origin are supposed to decay. Previous paleomagnetic study is limited to a two-step alternating field (AF) demagnetization up to 20 mT of a single fragment of unknown mass, for which no interpretation is proposed.

Kaba, Debreczen, Hungary.
Fell 1857, April 15, 2200 hrs
Stone. Chondrite Carbonaceous
Synonym : Debreczen.
Approx. recovered weight: 3 kg
After appearance of a fireball and detonations, a stone of about 3kg was found (J. von Torok (1858). The analysis shows an improbably high percentage of alumina, W. Wahl (1950).
