Tisserlitine 007 HED, achondrite (Eucrite melt breccia) (clast-rich melt rock) - 77.47 g - (1)

Tisserlitine 007 21.6654336° N, 0.8075866° W
Gao, Mali

Find: 2025 Feb

Classification: HED achondrite (Eucrite, melt breccia)

History: Reportedly, Naama Sidibuia and his group found the material in an area called Tayat Attafla near Tazouikert-Mali in February 2025.

Petrography: (K. Metzler, IfP) Clast-rich melt rock, consisting of subrounded eucritical lithic clasts (up to ~7 mm) with basaltic and gabbroic textures and mineral fragments (mostly pyroxene, plagioclase), embedded in a crystallized melt. Many pyroxene grains show shock-deformed exsolution lamellae. Accessories are a silica polymorph, ilmenite, Cr-spinel, and troilite.

Geochemistry: Mineral compositions and geochemistry: Mean mineral compositions: Low-Ca pyroxene (host): Fs61.1±1.0 Wo2.4±0.8 (Fs59.4-62.7 Wo1.6-3.8); Fe/Mn (at.): 34.3; n=10. Ca-rich pyroxene (exsolution lamellae): Fs27.8±1.5 Wo41.9±1.9 (Fs26.3-30.7 Wo37.7-43.7); n=10. Plagioclass: An88.4±3.9 Or0.5±0.4 (An80.2-92.1 Or0.1-1.2); n=12.

Classification: Eucrite (clast-rich melt rock)
