NWA 2965 was reclassified as being EL3 and paired with NWA 2828 EL3 as they came from the same find and were only different due to leaching out of matrix by the salt in the ground causing different colored interior at times.
Northwest Africa 2965 History and physical characteristics: Hundreds of fragments that weigh >100 kg were collected in the Algerian desert in 2004. Small fragments (~100 g) are commonly weathered to a dark brown with very dark weathering veins. Large pieces may retain portions of weathered fusion crust with only moderate to lightly weathered interiors. Petrography: (T. Bunch and J. Wittke, NAU) A completely recrystallized enstatite chondrite with polygonal to irregular grain outlines. The grain size varies from 0.02 to 0.7 mm. Round, curved, blocky objects contain coarser-grained orthopyroxene than in the matrix. No relict chondrules were observed in ~32 cm2 that were analyzed. Metal, daubreelite, and tiny, vermicular grains of graphite are also present and constitute <3 vol%. Mineral compositions: Orthopyroxene (Fs98.4±0.02), plagioclase (An17.8Or4.4), troilite with Ti = 0.91, Cr = 1.10, Zn = 0.6 (all wt%). Classification: Enstatite chondrite (EL6/7); minimal shock, variable weathering (W2–W5). It has absolutely no evidence of chondrules. Type specimen: A 24 g sample is on deposit at NAU. Turecki and Reed hold the main mass. |
