NWA 15170 is a lodranite meteorite of only 89 grams.
The lodranites are a type of meteorites forming a group within the primitive achondrites.
The reference fall is the Lodran meteorite that fell in 1868 in Pakistan..
These rare meteorites are composed for a large part of orthopyroxene (45 to 55 %), of magnesian olivine (40 %), of Fe-Ni alloy, of troilite, of clinopyroxene, of daubreelite, schreibersite, chromite and, accessorily, feldspars plagioclase and orthoclase, alabandite, graphite and apatite.
NWA 14809 is a carbonaceous meteorite of type CK5 of only 31 grams.
The reference fall is the Karoonda meteorite that fell in 1930 in Australia.
Writeup from MB 111 :
Northwest Africa 14809 (NWA 14809)
Algeria
Purchased: 2021
Classification: Carbonaceous chondrite (CK5)
History: Found in Algeria. Bought by Jean Redelsperger from Mohamed Elguirah in 2021.
Physical characteristics: Dark fragments.
Petrography: (J. Gattacceca, CEREGE) Chondrule with average apparent diameter about 800 µm set in a recrystallized matrix (grain size 15 µm). Olivine is the dominant mineral. Magnetite and sulfide are abundant in the matrix and chondrules, sometimes as composite spherical grains up to 200 µm.
