Aqueous alteration in CV carbonaceous chondrites

Several sections of CV chondrites belonging to the NASA Antarctic collection are being studied by our group in order to better understand the nature and physical processes occurred on the CV parent asteroid. We compare them with several sections of more common representative specimens from historic falls like e.g. Allende and Mokoia to find evidence of impact-induced heating and aqueous alteration. Once identified relevant features, we obtain mineralogical clues by using a Raman spectrometer.
