SIDERITE Iron Carbonate Amethyst Galleries

Sometimes variety names are given to intermediate members of these minerals such as mangansiderite for an iron rich rhodochrosite or magniosiderite for a magnesium rich siderite But this can be confusing Siderite is roughly the equivalent of calcite but with iron replacing the calcium The iron has little effect on most structural properties

Reaction mechanism for the replacement of calcite by

Carbonate reactions are common in mineral deposits due to CO 2 rich mineralising fluids This study presents the first in depth integrated analysis of microstructure and microchemistry of fluid mediated carbonate reaction textures at hydrothermal conditions In doing so we describe the mechanisms by which carbonate phases replace one another and the implications for the evolution of
