Writeup from MB 105:
Nuevo Mercurio (d) ~24°27’N, ~102°8’W Zacatecas, Mexico Purchased: 1982 Classification: Ordinary chondrite (L6) History: Purchased by a Mexican opal dealer from a local farmer in 1982, as part of a lot of Nuevo Mercurio stones. The meteorite was identified as distinct from the H chondrite fall by its lower magnetic susceptibility. Physical characteristics: One stone of 138.6 g covered by 30% fusion crust. The stone is weakly coated by iron hydroxides. Cut face shows light-gray interior with fresh metal specks and black shock veins. Petrography: (R. Bartoschewitz, Bart) Microscopic examination of a thin section shows strong recrystallized and strong shocked matrix (mosaicism and PDFs in olivine, maskelynite). Chondrules poorly preserved. Geochemistry: (R. Bartoschewitz, Bart, P. Appel and B. Mader, Kiel) Olivine Fa25.0±0.3 (n=13); pyroxene Fs21.2±0.5Wo1.8±0.2 (n=18). Kamacite Ni=5.3-7.1, Co=1.0-1.1 wt.-%). Magnetic susceptibility (R. Bartoschewitz, Bart) log χ (× 10-9 m3/kg) = 4.94. Classification: Ordinary chondrite (L6) Specimens: 21.4 g on deposit at Kiel, main mass Bart. | ||||||||||||||||||||||||||||||||||||||||
