About 45 kg of the meteorite was recovered. It turned out it was a rare type meteorite, a pallasite, the very first of its kind found in the Nordic countries. The summer went, but then in september the same year, another pallasite was found! (the 2nd one ever). This time in the north of the Nordic countries. This one was found (not a fall) at the high plains near Alta, in Norway's northernmost province of Finmark. It got the name Finmarken from the province, in Norway known as the Alta-meteorite. A total of 78 kg was recovered. So far these are the only recognized pallasites of the Nordic countries. A bit strange they both popped up in the same year, only 3 months apart? In my meagre collection of information about these meteorites, I have an article which ask if there is a connection between these two. The direction of the trail of the Marjalahti fall points in a northwesternly direction (towards Finmark). They are both main group pallasites, they have the same divergent rare metal abundances (toghether with two others), they both contain both round and polyhedral olivine grains. Is this pure coincidence? Are there any new results about the possible connection between these two interesting meteorites? Bjørn Sørheim Received on Thu 18 Jan 2001 10:55:58 AM PST |
