Chondrite Ungrouped Meteorite NWA 13202 -polished slice- 5.99 grams

NWA 13202 Chondrite Ungrouped 5.99 gram Slice The specimen consists of two distinct interspersed components with overall proportions of ~75% metal and ~25% silicate-rich material. Metal-rich regions (up to 0.5 mm) are composed of 95% kamacite with 5% taenite, and contain fine grained metal plates ranging from 100 to 500 μm in diameter. Silicate-rich regions (up to 0.5 mm) contain a variety of chondrules (with apparent diameters ranging from ~100 to 1500 μm). Most chondrules are glass-bearing (PP, PO, POP and barred pyroxene types) but some are cryptocrystalline. Accessory phases in silicate-rich regions include kamacite, taenite, chromite, troilite, merrillite and chlorapatite. Here is an amazing slice of a super rare meteorite.  It consists of mostly metal but has scattered chondrules throughout and is highly reflective on the polished side. Its truly one of a kind and not including the deposit at UNM, this slice makes up about 1.5% of this classification. It was very hard to photograph being so reflective but it should give you a good idea on how interesting this piece really is. Meteorites are one the leading sources of scientific evidence that give us an insight into the formation of our solar system.  By studying the composition of elements present inside meteorites, we are able to paint and increasingly sharper picture in order to answer the biggest question of all, "How did we get here?"
