Betreff: [meteorite-list] Catalog of the recovered Bassikounou masses released

> We are pleased to announce that the Descriptive Catalog on the Recovered
> Masses of the Bassikounou Meteorite Fall is now available as a
> non-commercial download.
>
> The catalog lists 108 single masses of a combined weight of 62.186kg
> (including the 6.120kg main mass) individually and another 31.665kg in lots.
> More than 80 individual masses are pictured. The final TKW of the Bassikounou
> meteorite fall is 93.851kg.
>
> In the latest phase of this undertaking we have often been approached by
> collectors explaining that regarding to their observations the TKW should be
> much higher. To prove their point they showed us images of single
> Bassikounou meteorites or complete lots they were offered recently. In 99% of these
> cases we had cataloged the particular masses before either individually or
> under a certain lot.
>
> In this context it might be interesting for some of you, that many
> meteorites change hands already before they get distributed. Moroccan sellers
> equip their colleagues with commission material to visit Europe, or they simply
> exchange certain batches of material between one another. This is the
> reason why one and the same meteorite can be offered to you from different
> sellers from the same NWA country successively.
>
> During our research we were able to follow an exemplary Bassikounou mass
> on its journey from the local finder, to a distributor in Morroco, to a
> meteorite fair in France, to a European mineral dealer and finally to a
> collector in Canada. During the stations of the journey this particular meteorite
> was offered no less than 12 times under different circumstances and with
> different photos.
>
> This in mind it is no wonder that people think there is much more material
> circulating than actually is. Our experience lead us to the conclusion
> that many recent meteorite falls that produced showers are largely
> overestimated in their total weight.
>
> We hope that our investigation may aid the understanding and recovery of
> future meteorite falls in isolated areas. And we are positive, that our
> undertaking helps to sensitize finders as well as distributors in Mauritania
> and Morocco to preserve the information that is connected to the meteorites
> they trade.
