Diffusionglaucophane
Diffusionglaucophane is a rare silicate mineral belonging to the amphibole group. Its chemical formula is Na2Mg3Al2Si8O22(OH)2. It is a member of the glaucophane-riebeckite series, often found as an end-member or close to it. The mineral is characterized by its distinctive blue to violet color, though this can vary depending on the presence of trace elements. The "diffusion" in its name refers to the complex solid solution processes that lead to its formation and the variations in its composition.
This mineral typically forms under high-pressure, low-temperature metamorphic conditions, commonly found in blueschist facies rocks. These
Notable occurrences of diffusionglaucophane have been reported in various locations globally, including Japan, Italy, and the
