Writeup from MB 111:

Chug Chug 124        22°29.84’S, 69°2.67’W

Antofagasta, Chile

Find: 13 Oct 2018

Classification: Ordinary chondrite (L6, melt rock)

Petrography: Coarse-grained breccia composed of rock fragments of 0.5-2 cm in size joined together by melt rock veins up to 1 mm in width. The fragments are mostly comprised by fine-grained metamorphosed rock which contains subhedral crystals of olivine (20-50 µm in size) with minor (~15 vol. %) interstitial xenomorphic pyroxene and feldspar. Minor phases are troilite and Fe,Ni metal; chromite is accessory. Rare relict chondrules were observed. About 15 vol. % of the rock fragments are composed by medium- to coarse-grained recrystallized chondritic rock with relict chondrule fragments (metamorphic Type 6). Some of the fragments in the breccia are composed of both fine-grained and chondritic rocks. Olivine in the all rock fragments has undulatory optic extinction and planar fracturing, rare grains indicate mosaicism. The veins compose of silicate melt rich in fine scattered troilite globules and silicate fragments; widest veins contain troilite-metal globules. At places the fragments and melt rock veins are crossed by troilite-metal veinlets.

Classification: Based on texture and composition the meteorite is classifyed as slightly weathered, moderately shocked L6 melt rock (S4, W1).
