    Acid test: This is an important test and can immediately identify whether the floor in question is marble, granite, or some other material. One drop of diluted solution of hydrochloric acid is applied to the floor. If the acid bubbles or fizzles, it’s marble; if there is no reaction, it is likely granite.

  • Iron isotope fractionation during leaching of granite and

    During the granite experiments, alteration of biotite to chlorite, followed by dissolution of chlorite, were likely the dominant processes, whilst in the basalt experiments, dissolution of pigeonite was likely the principal source of Fe. Variations in pH during the hydrochloric acid experiments were minimal, remaining below 0.5 at all times.
