- Description
- Vis-NIR reflectance spectra of the Kebri Dehar (Ogaden, Ethiopia) basalts altered in hot conditions with globally increasing aridity since Late Oligocene. The samples are cobble fragments sampled from the same outcrop. The experiment contains spectra of the powder of the alteration rind and of the internal part of the samples.
