About Rodingite
Name:
Named after the type location, the Roding River, NZ by Bell, Clark and Marshall in 1911.
A metasomatic rock primarily composed of grossular-andradite garnet and calcic pyroxene (diopside, etc); vesuvianite, epidote, scapolite, prehnite and iron ores are characteristic accessories. Rodingite mostly replaces dykes or inclusions of gabbros and other basic rocks within serpentinized ultramafic bodies. May also replace other basic rocks, such as basaltic rocks or amphibolites associated with ultramafic bodies.
Another definition: "A massive dense buff to pink rock typically rich in grossular garnet and calcic pyroxene, and enveloped in serpentinite. Epidote, vesuvianite, and other calcium-rich minerals are commonly present. It is formed by metasomatic alteration of a protolith that, in many cases, was a dike rock, as shown by preservation of structures. The name was applied by Bell in 1911."

Mineralogy of Rodingite
Essential minerals - these are minerals that are required within the classification of this rock:
Andradite-Grossular Series | A petrological term for Andradite-Grossular Series. |
High-calcium pyroxene | A petrological term for pyroxene high in calcium, invariably these will be clinopyroxene minerals. |
Non-essential minerals - these minerals are common, sometimes major components, but are not always present:
Epidote | (CaCa)(AlAlFe3+)O[Si2O7][SiO4](OH) |
Magnetite | Fe2+Fe3+2O4 |
Scapolite | This term generally refers to just the marialite-meionite series, not the full scapolite group, ... |
Vesuvianite | Ca19Fe3+Al4(Al6Mg2)(◻4)◻[Si2O7]4[(SiO4)10]O(OH)9 |
