NWA 4301 is an exceedingly rare Ungrouped Enstatite-rich Achondrite found in Algeria in 2006 by nomadic tribesman. NWA 4301 is nearly identical to Zakłodzie, both in mineral composition and terrestrial age, about 300 years (The same scientist at NSF Arizona AMS Laboratory measured the terrestrial age dates of both meteorites). If they had not fallen 3000 km apart, NWA 4301 would have been considered a pairing. While that is unlikely, scientists agree they are most likely source launch-paired! The Total Known Weight of NWA 4301 consists of a single 685 gram stone.
"This meteorite [NWA 4301] is essentially a clone of Zakłodzie, for which…a very young terrestrial age of several hundreds of years [was found] (even though it is weathered to some extent). I presume that the terrestrial ages of these two are analytically distinguishable, but it could still be that they are launch-paired."
"NWA 4301 seems much fresher than Zakłodzie."
"I believe that the [terrestrial ages] are permissive of both stones being part of the same fall, but landing 3000 km apart in Poland and Algeria. Of course there is a very large uncertainty, so it does not prove it, but the two meteorites are remarkably similar and different from anything else."
