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 :)

Find/Fall Anniversary
1009 grams.   H3-6

TKW 175 kg. Observed fall, August 4 or 5, 1998, in the western Sahara.


 


Herbert writes:
The Zag meteorite fell in the Lahmada region of Western Sahara on August 4 or 5, 1998. About 175 kg of this brecciated H3-6 chondrite were recovered. Researchers later discovered that Halite (salt) crystals are embedded in this breccia, and within the Halite, liquid water and amino acids were found.

This 1009 gram specimen shows several generations of fusion crust from multiple breakup events: The "Bottom" side (photo #3) shows thick primary fusion crust and well developed regmaglypts, the "East" side (photo #1) shows smooth secondary crust, while the "West" side (photo #2) shows both secondary as well as thin, brownish tertiary crust. Slickensides are visible on the top left of photo #2. Photo #4 is a closeup of a small, broken area that reveals the brecciated structure of this meteorite.

The Swiss collector from whom I got this specimen nicknamed it "The Matterzag", for it's similarity with the famous Matterhorn mountain (photo #6 by Andrew Bossi. Attribution CC-BY-SA-2.5).

If it's an observed fall, why is the date uncertain?

Great, Herbert, great! And I remember it like it was yesterday. Some samples have their own story besides the meteorite fall story :-).
