Writeup from MB 102:
Dhofar 1754 (Dho 1754) 19°23.58’N, 54°33.25’E Zufar, Oman Found: 2001 May 2 Classification: HED achondrite (Howardite) History: A single fusion-crusted rock of 580 g was found near Dhofar 930 by an anonymous finder May 2, 2001. Petrography: In thin section the rock has two distinct lithologies: one is basaltic and the other is diogenitic (each about 50 vol% in the section studied). Thus the rock is a breccia. The low-Ca pyroxene is variable in composition. Most are Fs22-34; more Fs-rich olivine (~Fs45-60) probably belongs to the eucritic lithology. Typical plagioclase has a composition of An82-95. The meteorite is a howardite. Geochemistry: 42 randomly selected low-Ca pyroxenes were analyzed by SEM-EDS: The low-Ca pyroxene is variable in composition (~Fs22-60) with mean Fe/Mn= 32.5. In the distribution a clear peak around Fs23-25 is found, which is typical for diogenites; more Fs-rich pyroxene (~Fs40-60) probably belongs to the eucritic lithology. Plagioclase has a composition of An82-95. Classification: Pairing with Dhofar 930 (polymict eucrite) is unlikely because of the high abundance of Fs-poor (Fs<30) low-Ca pyroxene within Dhofar 1754, which has not been reported from Dhofar 930. | ||||||||||||||||||||||||||
