Left: wavelength position of the centers of the two absorption bands computed using Cloutis et al. (1986). The enclosed regions correspond to the band centers computed for the H, L, and LL chondrites, respectively (de León et al. 2010). Right: band area ratio (BAR) versus band I centers. The regions enclosed by continuous lines correspond to the values computed for basaltic achondrites, ordinary chondrites (OC), and olivine-rich meteorites (Ol) (Gaffey et al. 1993).
