词条 Rodingite
释义

  1. References

Rodingite (or Granatite obsolete) is a metasomatic rock composed of grossular-andradite garnet and calcic pyroxene; vesuvianite, epidote and scapolite.[1] Rodingites are common where mafic rocks are in proximity to serpentinized ultramafic rocks. The mafic rocks are altered by high pH, Ca2+ and OH- fluids, which are a byproduct of the serpentinization process, and become rodingites. The mineralogy of rodingites are highly variable, their high Ca, low Si and environment of formation being their defining characteristic.[2] Rodingites are common in ophiolites, serpentinite mélanges, ocean floor peridotites and eclogite massifs. Rodingite was first named from outcrops of the Dun Mountain Ophiolite Belt in the Roding River, Nelson, New Zealand.[3]
