Re: [meteorite-list] Terrestrial meteorite
Thanks to all who conributed to the discussion with insightful comments. Of course we will answer, but a mail to the list is not the appropriate place. We will write a paper which will be peer reviewed giving more informations than what can be written in an abstract.

It is just one (remote?) possibility for the origin. There are several types of meteorites that plot on or near the TFL, but that does not mean they are from Earth. There is a growing number of ungrouped achondrites that indicate significant basaltic to andesitic volcanism on early solar system bodies. A crystallization age of NWA 13188 would be important to have to help prove it is from Earth -- I haven't seen the 2023 Goldschmidt abstract (only the 2022 MetSoc abstract). Has an age been determined yet? Carl * Carl B.

Neglecting the effects of the Earth's atmosphere, it would take five times as much energy to launch a basaltic rock off the Earth as it would to launch the same mass rock off Mars. Except for Black Beauty, essentially every shergottite has been severely shocked during launch off Mars, transforming the crystalline plagioclase into maskelynite. (A few shergottites with no maskelynite were shocked-heated even more strongly.) A terrestrial basalt launched off Earth would be heavily shocked or completely impact melted. This does not seem to be the case for NWA 13188. I don't think it is terrestrial.

Unfortunately for me at the time, we decided that any strong identification would rely on details of silicate chemistry that are tough to measure through ground-based remote sensing. But we were certain that such bodies must exist. On the same subject, the moon will be a great place to search for terrestrial meteorites, and may prove to be the best place to investigate the conditions of early Earth. Heck, we might even find fossils.
