Adrar 017        27°7.41' N, 0°47.15' E
Adrar, Algeria
Purchased: 2025 Apr
Classification: Lunar meteorite (troctolitic anorthosite)
Physical characteristics: The meteorite is a large 18.2 kg gray stone.
Petrography: The meteorite exhibits a brecciated texture dominated by cm-size grayish-greenish clasts in a dark gray matrix. Melt pockets within anothositic matrix can also be found. Two analysed fragments chosen from the most common lithologies, one grey-greenish coloured and one dark grey corresponding to the ground-mass, have both a troctolitic anorthosite composition based on modal mineralogy (through SEM-BSE images on the grey-greenish fragment) and calculated normative composition (through SEM-EDS elemental maps on the darker fragment), with the following mineral abundances: plagioclase 86.9 vol%, olivine 8.0 vol%, pyroxene 5.2 vol% (for the darker clast) and plagioclase 82.0 vol%, olivine 11.0 vol%, pyroxene 7.0 vol% (for the grey-greenish fragment). Minor phases detected are oxides with variable composition, Fe-sulfide. FeNi metallic alloy, Ca-carbonate and Ba-sulphate thin veins are also found.
Geochemistry: Olivine Fa23.7±7.9 (Fa13.2-41.6, FeO/MnO= 85.0±8.2, n=35); low-Ca pyroxene Fs18.7±6.2Wo3.4±1.1 (En68.7-85.7Fs12.2-27.1Wo2.1-4.3, n=4), pigeonite Fs18.3±6.0Wo7.3±3.9 (En60.8-83.6Fs10.8-24.9Wo5.1-14.3, n=5); high-Ca pyroxene Fs20.3±4.9Wo28.6±12.1 (En39.4-58.9Fs13.9-24.7Wo16.3-41.5, n=4); calcic plagioclase An96.8±0.6 (An95.1-97.9Ab2.1-4.8Or0.0-0.1, n=31); oxides with intermediate spinel-hercynite composition (atomic ratio Mg# = 60.3-61.3) and intermediate magnesiochromite- hercynite composition (atomic ratio Cr# = 23.4-66.3 and Fe# = 30.8-52.7), FeNi metallic is kamacite with Ni=2.0 wt% (n=1).
Classification: Lunar (troctolitic anorthosite, breccia) based on Stoeffler et al. (1980)
Specimens: Mark Lyon holds the main mass. One end-cut sample (51 g) and one slice (17 g) at MSN-FI, University of Firenze, Italy.

About Us

The WWMeteorites team (for "WorldWide Meteorites" - Meteorites from around the world) was created in 2003 with the primary goal of traveling around globe in search of these fascinating celestial objects, and make them available for Science... and Collectors. Since 2017, the team has established its base camp on the island of Unst (Shetland, UK).

With four or five trips per year on average, the number of finds (in countries as diverse as Tunisia, Spain, Qatar, the Sultanate of Oman ...) has quickly become important. WWMeteorites therefore collaborates with several laboratories that analyze, and classify the new meteorites, mainly the Museum Fur Naturkunde (Berlin), the CEREGE (University of Aix-Marseille), and the Appalacjain State University (North Carolina). WWmeteorites (under the name of its founder, Fabien Kuntz.)  have already more than 500 meteorites listed in the Meteoritical Society Database.

In order to have a classification and an official referencement established, as well as to allow the long-term research on the meteorites, a part of 20% of each find by WWmeteorites is deposited in a lab
