  • dissolution of titanuim and mica of basalt

    Basalt . Alkali basalt is a fine-grained dark color volcanic rock composed of phenocrysts of olivine, titanium rich and iron oxides (Fig. 4.40). Alkali basalt is relatively poor in silica and rich in sodium. It is silica unsaturated and contains feldspathoids (nepheline, leucite), alkali feldspar and phlogopite (magnesium mica) in the groundmass.
