As magmas rise toward the surface, they traverse regions of the mantle and crust with which they are not in equilibrium; to the extent that time and the intimacy of their physical contact permit, the melts and country rocks will interact chemically. We have modeled aspects of these chemical interactions in terms of ion-exchange processes similar to those operating in simple chromatographic colu...

Abstract Hyperspectral remote sensing already is important in geoscientific research the fields of geology, soil, exploration and mining. New hyperspectral satellite systems are operation (e.g. PRISMA DESIS; Caporusso et al. 2020; Alonso (Sensors 19(20):4471–4515, 2019)) more planned e.g. European Copernicus Next Generation Satellite CHIME (Nieke Rast 2018). The German system EnMAP was successf...
