THE KEY BANDS IN THE mid-IR • The 3 m absorption band associated with OH hydroxyl groups is evident for CM chondrites, but in different degrees: – The depth of the OH bands seems to be directly related with the extent of aqueous alteration
CO and CV CHONDRITE GROUPS • The absorption bands are also present, but in distinguishable location as consequence of different mineralogy • IR spectra of CO, and CV carbonaceous chondrites analyzed so far. Kainsaz, ALH83108, and ALHA77003 are CO3 chondrites. • Over 30 m the results should be taken with caution Trigo-Rodriguez et al. (2012)
