Comparison of the energy dispersive X-ray spectra of amorphous and crystalline phases. Comparison is of amorphous material resulting from the dissolution of sodic-calcic amphibole (a) and cpx (b) with their crystalline source minerals (insets). In both amorphous phases significant amounts of alkalis, Al as well as Fe are present. The expected element transport capacity of these materials is several times larger than that of aqueous solutions. See text for discussion. Ga K and L line intensities are due to Ga ion implantation during FIB milling. Cu K intensity comes from the TEM copper grid. Pt intensity is due to redeposited Pt during FIB milling
