    Aragonite will generally develop only at hot springs whereas most other calcareous growths will be Calcite. Calcite may form as an undesirable coating on top of another mineral. The calcite can be easily burned off by soaking it in acid which will cause it to effervesce and eventually dissolve leaving the mineral below exposed.

  • The calcite → aragonite transformation in low-Mg marble

    Experimental transformation of a rather pure natural calcite marble to aragonite marble did not proceed via the expected straightforward polymorphic replacement. Instead the small amount of Mg in the starting material (0.36 wt ) was excluded from the growing aragonite and diffused preferentially into the remaining calcite grains producing Mg-rich calcite rods that persisted as relicts.
