Writeup from MB 100:
Jiddat al Harasis 514 (JaH 514) 19°31.597’N, 55°11.725’E Zufar, Oman Found: 20 Jan 2008 Classification: Enstatite chondrite (EL4) History: A single stone was found during a search for meteorites by A. Al-Kathiri, E. Gnos, A. Grimberg, B. Hofmann, E. Janots during a search for meteorites. Physical characteristics: Single dark brown individual without fusion crust, deep cracks due to weathering, with a mass of 20.185 g. Petrography (E. Gnos, MHNGE; B. Hofmann, NMBE): The dominant silicate mineral is enstatite with a mean composition of Fs2.0Wo0.7 . Some grains are essentially pure enstatite. Mean chondrule size is 0.9 mm. Feldspar is very fine-grained and albite-rich. Cr-bearing troilite and daubreelite are other common phases, kamacite is largely oxidized, schreibersite is also present. Ferroan alabandite (Mn0.39Fe0.49Mg0.11)S is only present as rare small relicts where fully enclosed in troilite. Geochemistry: Bulk rock elemental ratios (in g/g, based on combined ICP-OS and ICP-MS) are Mn/Mg 0.010, Na/Mg 0.043, Mn/Cr 0.49. The bulk Zn content is <30 ppm (31 ppm by XRF). Classification: Enstatite chondrite, EL4, shock stage S2, weathering W3. Classification based on presence of Fe-alabandite, low Zn content, and Mn/Mg and Na/Mg ratios in EL range. Specimens: All at NMBE. | ||||||||||||||||||||||||||||||||||||
