Writeup from MB 91:
Ilizi 26°45′N, 08°53′E Ilizi, Algeria Find: 1991 Ordinary chondrite (H4) History: U. Messerli of Hermringen, Switzerland, found this single stone in the Ilizi area of Algeria in 1991. The sample was submitted to NMBE for classification in 2003. The stone was found among many terrestrial rocks. The terrestrial rocks show evidence that early humans may have used them as tools. It is suspected that the meteorite, due to one surface being very flat and smooth, may also have been used a tool during the Neolithic. Physical characteristics: Dark brown rounded stone without fusion crust, 5.5 × 5 × 4 cm in size, 185 g mass. One side displays a very flat and smooth surface (~4 × 4 cm). The interior shows chondrules up to 5 mm in diameter. Petrography: (E. Gnos, UBE; B. Hofmann, NMBE) Average olivine (Fa18.6), average orthopyroxene (Fs17.5Wo1.25). Type specimen: A 21.5 g type specimen and 1 polished thin section are on deposit at NMBE. U. Messerli holds the main mass | ||||||||||||||||||||||||||||
