Writeup

Writeup from MB 107:

Catalina 278 24°55’54.2"S, 69°44’15.9"W

Antofagasta, Chile

Find: 2017 Nov 08

Classification: Ordinary chondrite (LL3.4)

Petrography: (J. Gattacceca, CEREGE) Tightly packed chondrules. Clasts with cluster chondrite texture as defined by Metzler (2012). Based on the structural order of the polyaromatic matter assessed by Raman spectroscopy, this meteorite appears to be as metamorphosed as Chainpur (LL3.4). The Raman spectroscopy parameters of interest are FWHM-D (cm-1)=155.8±7.6, ID/IG=1.02±0.04 (see Bonal et al., 2016, figure 7).

Geochemistry: Olivine Fa_13.9±9.6, Fa PMD=65%, range Fa_1.1-29.7(N=16), Cr₂O₃ in ferroan olivine 0.14±0.11 wt% (N=15). Low-Ca pyroxene Fs_15.1±6.9Wo_2.1±1.9, range Fs_1.1-22.2(N=10).

Classification: LL3.4. Subtype from Raman spectroscopy.

Specimens: 182 g and a polished section at CEREGE. Main mass at MMC.
