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 Fa13.9±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 Fs15.1±6.9Wo2.1±1.9, range Fs1.1-22.2 (N=10).

Classification: LL3.4. Subtype from Raman spectroscopy.

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