2021 Fall Date Project

The MPOD Caretakers want to present meteorite falls on their fall dates. For example, Sikhote Aline on 12 February.

This Project will not dip into the MPOD archives so the Caretakers will appreciate anything you can contribute.

To reserve a date just let us know. Thank you in advance :)

3.23 grams.   C2-ung

TKW 4 kg. Observed fall 25 August 2020, Morocco.


Stephan writes:
In many ways this meteorite is extraordinary. It has no CAI's (probably place of origin > 10AU). Upon contact with water, the matrix melts away. Oxygen isotopy δ18 O shares similarity of CI and CY meteorite values; However, Δ17 O is below that of CI and CY. There is no overlap with other groups of meteorites. Tagisch Lake is arguably the closest in some ways. Much research will certainly be done on this meteorite, and some literature will follow.

Oh sorry - the fragment you ment. Shure, it looks like CAI, but a close up picture would show you the slightly green yellow colour and small crystals - AOA - suggestion.

The whit clasts could be am*boid olivine/ aggregate. In the case of the 7 gram individual, it could also be impurities or meltdowns in the crust during the ablation process just before the inhibition zone, without the AOA being able to be completely converted during melting.

Very nice collection of Tarda, Stephan!! No CAI`s inside, but what could be the visible white clasts in picture #4?
