    iron (Nilsen and Kerr, 1978). There is an apparent upward enrichment in ferric iron, aluminum, and titanium and depletion of silicon, ferrous iron, and alkali and alkaline-earth metals. The vertical variations in chemical and mineral content of this unit are interpreted as products of subaerial weathering rather than hydrothermal alteration ...

  • Basalt - Wikipedia

    Basalt is a mafic extrusive igneous rock formed from the rapid cooling of magnesium-rich and iron-rich lava exposed at or very near the surface of a terrestrial planet or a moon. More than 90% of all volcanic rock on Earth is basalt. Basalt lava has a low viscosity, due to its low silica content, resulting in rapid lava flows that can spread over great areas before cooling and solidification. Flood basalt describes .

    In addition, the hydration reaction accompanied the basalt fiber dissolution, and insoluble hydroxides formed by calcium and iron covered the fiber surface. A thin hydrated layer (corrosion shell), which covered the complete filament surface, was formed (State B) with continuation of the hydration reaction.

  • In which solvent can TiO2 can be dissolved easily?

    The solubility of titanium dioxide is related to solutes. It is insoluble in dilute alkali, dilute acid, but soluble in hot concentrated sulfuric acid, hydrochloric acid, hydrofluoric acid and nitric acid but not in the form of TiO2 but as a salt like sulfate, chloride, nitrate etc. Titanium dioxide can melt in the alkali (sodium hydroxide,...

  • Titanium Dissolution from Indonesian Ilmenite - IJENS

    from 50 % to 75%. Almost 85 % of titanium and 30 % of iron were dissolved into the aqueous sulfuric acid solution when the decomposed ilmenite were dissolve into 75 % sulfuric acid solutions at dissolution temperature 125 o C and dissolution time 2 hours. From the kinetical study, the titanium dissolution from

  • Dissolution and secondary mineral precipitation in basalts ...

    May 18, 2017 · Aluminosilicates (clay or zeolite) also precipitated as secondary mineral phases. For our samples, rock dissolution mechanisms dominate secondary mineral precipitation, during the CO 2 ‐water‐rock reactions, thereby creating new pores. In addition, rock dissolution was found to affect the rigidity of the basalt samples negatively.
