What it is
Chain silicates where SiO₄ tetrahedra link end-to-end in single or double chains. This category includes the rare and beautiful bustamite, a manganese-calcium chain silicate with a soft pink color.
How it forms
Forms in contact-metamorphic zones where manganese-rich rocks meet hot magmatic fluids.
