[meteorite-list] Terrestrial meteoriteAlbert Jambon classified NWA 5363 which is paired to NWA 5400, both of which plot on the TFL, leading many to speculate an earth origin. Here is a short article about the meteorite: https://meteoritegallery.com/nwa-5363-ungr-achondrite/ Gary Fujihara Big Kahuna Meteorites 105 Puhili Pl, Hilo, HI 96720 (808) 640-9161 http://www.ebay.com/sch/fujmon/m.html > On Jul 12, 2023, at 12:39 PM, mlblood--- via Meteorite-list <meteorite-list at meteoritecentral.com> wrote: > > Didn?t the Hupe Brothers offer an Earth origine meteorite some years back? > Michael Blood > > > > >> On July 12, 2023 at 7:21 AM drtanuki via Meteorite-list <meteorite-list at meteoritecentral.com> wrote: >> >> >> >> >> >> https://www.hou.usra.edu/meetings/metsoc2022/pdf/6294.pdf >> >> NORTHWEST AFRICA 13188: A METEORITE FROM THE EARTH?

Based on the observation of a fusion crust, texture and mineralogy, NWA 13188 was classified as an ungrouped achondrite [1]. This single stone was purchased by AJ from a Moroccan meteorite dealer at Ste Marie aux Mines Mineral Show in June 2018. It is an igneous rock with overall subophitic texture and typical silicate grain size of 350 ?m. The mineralogy is dominated by plagioclase (49 vol%) and pyroxene (26 vol%), as well as fine-grained mesosta-sis of plagioclase, pyroxene (18 vol% of the mesostasis), accessory FeTi oxides and glass. Vesicles with typical size 250 ?m represent 8 vol% of the rock. No metal is observed. ... >> >> Northwest Africa 13188 >> https://www.lpi.usra.edu/meteor/metbull.php?code=71664 >> >> >> >> >> >> >> >> >> On Wednesday, July 12, 2023 at 11:11:10 PM GMT+9, Michael Farmer via Meteorite-list <meteorite-list at meteoritecentral.com> wrote: >> >> >> >> >> >> Unfortunately paywall >> >> >> Sent from Yahoo Mail for iPhone >> >> On Wednesday, July 12, 2023, 2:05 AM, Albert Jambon via Meteorite-list <meteorite-list at meteoritecentral.com> wrote: >>> There was a presentation at the Goldschmidt Conference in Lyon this week.
