NWA 18064 - LL4 Ordinary Chondrite

NWA 18064 is an LL4 Ordinary Chondrite from Algeria, reportedly found in March 2017 by nomad meteorite hunters in the Sahara and later purchased in Ouarzazate, Morocco, in December 2019. As an LL Chondrite, it has low total iron and low metallic iron compared with H and L Chondrites. Its type 4 classification indicates moderate thermal metamorphism on its parent asteroid, preserving many Chondritic features while also showing partial recrystallisation.

NWA 18064 is recorded as a single piece with fusion crust covering approximately 90 percent of the surface. Specimens are expected to show the features of an LL4 Ordinary Chondrite, including a stony grey to brown interior, visible or partly preserved chondrules, and relatively low metal content. The combination of fusion crust and type 4 texture gives the material strong display and educational value, especially for collectors interested in lower-metal Ordinary Chondrites.

Studying NWA 18064 provides insight into the LL Chondrite parent body, moderate thermal alteration, and the preservation of Chondritic textures in desert meteorite finds. For collectors, it offers a recognised classified meteorite with Algerian provenance, single-stone history, and classic LL4 character. Each specimen represents ancient asteroid material formed over 4.5 billion years ago, preserved as part of a valid Northwest African meteorite find.
