NWA6452 CV3
Here is a brief description for classification :
The meteorite is tentatively classified as an oxidized CV-like carbonaceous chondrite.
It consists of equal proportion
of chondrules and matrix; CAIs and AOAs are common, but minor.
Type I chondrules are dominant; chondrule olivines are enriched in FeO compared to
low-Ca pyroxene (Fa = 5.1±2.9, n = 46 vs. Fs = 1.6±0.6, n =25).
Many chondrules are surrounded by coarse-grained igneous rims.
Low-Ca pyroxene and opaque nodules in chondrules are replaced by ferroan olivine
to varying degrees. Fine-grained rims around chondrules are commonly crosscut by
veins of ferroan olivine (Fa60), magnetite and sulfides.
Most CAIs are fine-grained, spinel-rich. Spinel is enriched in FeO; nepheline and
sodalite are common.
The meteorite matrix is composed of micron-sized ferroan olivine (Fa60) and nepheline
with submicron inclusions of ferroan olivine.
In contrast to matrices of typical CV chondrites, Ca,Fe-rich pyroxene-andradite nodules
in matrix are absent.
