Introduction: Hydrated minerals preserve a record of past aqueous conditions on Mars. Recently, phyllosilicates, hydrated sulphates, hydrated silica have been detected in surface rocks by near-infrared spectrometers on orbiting spacecraft [1-4]. At the kilometer-scale resolution of the OMEGA instrument, phyllosilicate exposures are widespread and number in the dozens [5,6], while early discover...

Abstract This contribution provides insights into ocean-floor hydrothermal metamorphism of the fast-evolving Dinaridic Neotethys. Mineralogical, geochemical and Sr isotope data collected from altered ophiolites non-ophiolite basalts/andesites tuffs active continental margin are consistent with alteration trajectories that reflect host-rock composition. suggests fluxes were restricted within a s...

Abstract The paragenesis and composition of bavenite–bohseite were investigated in fifteen granitic pegmatites from the Bohemian Massif, Czech Republic. Three types distinct their relation to primary Be precursors, mineral assemblages, morphology origin recognised: (1) hydrothermal crystallised miarolitic pockets residual pegmatite fluids; secondary two types: (2) a proximal type restricted spa...
