Writeup from MB 104:
Sahara 00350 (Sahara) Find: 2000 Classification: Ordinary chondrite (L6) History: This 14.2 gram piece from Scott Brey is the only material of Sahara 00350 that of which Brey or Labenne are aware. The estimated size of the main mass of the ordinary chondrite could be 200 g based on this slice, but the main mass is unknown and may have been much smaller. Physical characteristics: Description based on 14.2 g complete slice. Sawn surface shows network of dark shock veins. Few chondrules visible, metal grains up to 2 mm. Petrography: (L. Garvie, C. Fudge and T. Sharp, ASU) Matrix largely recrystallized, with a few recognizable porphyritic and barred olivine chondrules. Plagioclase abundant up to 200 ?m. Sparse distribution of metal and troilite. Olivines show mosaicism and planar deformation features consistent with shock stage S5. Shock melt vein approaches 3.0 mm, and contains abundant blue ringwoodite and green wadsleyite confirmed with Raman spectroscopy indicative of S6 shock. Geochemistry: (C. Fudge, ASU) EPMA: Fa24.8±0.1 FeO/MnO: 46.7±1.9 n=10; low-Ca pyroxene Fs20.9±0.1Wo1.6±0.2 FeO/MnO: 29.3±1.6 n=10; high-Ca pyroxene Fs8.4±0.2Wo44.3±0.6 FeO/MnO: 20.5±1.2 n=3 Classification: Ordinary chondrite L6, S6, W2 Specimens: 14.2 g and one thin section at ASU. Reportedly collected in the same location as Sahara 98222 and Sahara 00293. | ||||||||||||||||||||||||||||||
