...Daniel Marshall; Hans-Rudolf Pfeifer; Johannes C. Hunziker; David Kirschner Abstract The Mont-Chemin region at the NE extreme of the Mont-Blanc massif, Canton Valais, Switzerland is predominantly comprised of the granitic rocks of the Mont-Blanc intrusive rock suite and the Mont-Blanc basement...

... then concluded this work with the monograph ‘Apercu géologique sur la Chaine du Mont Blanc en rapport avec le traject probable d’un tunnel pour la nouvelle ligne de chemin de fer’ , published in 1881. His main aim was to predict correctly ‘quelles roches et dans quelles conditions de stratification on aurait...

... spectra, we focus on a subset of the multispectral data set for which additional constraints on the composition of surface materials are available from other rover instruments, with an emphasis on sample sites for which detailed mineralogy is provided by the results of CheMin X-ray diffraction analyses...

... Santa Monica Mountain, near Griffith Park (Los Angeles, California), was investigated as a mineralogical analog to smectites discovered on Mars by the CheMin X-ray diffraction instrument onboard the Mars Science Laboratory (MSL) rover. The martian clay minerals occur in sediment of basaltic composition...
