Rodingite is a metasomatic rock composed of grossular-andradite garnet, calcic pyroxene, vesuvianite, epidote and scapolite. 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 mineral content of rodingites is highly variable, their high calcium, low silicon and environment of formation being their defining characteristic. 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.

| - Rodingit ist ein metamorphes Gestein, das durch metasomatische Reaktion zwischen einem Serpentinit und einem silikatreichen Ausgangsgestein entstanden ist. Rodingite wurden 1911 nach einem Vorkommen am in Neuseeland erstmals beschrieben. Rodingite treten oft als zentimeterdünne Lagen am Kontakt zwischen Serpentiniten und silikatischen Gesteinen oder als feinkörnige Gänge, Linsen und Adern in Serpentiniten auf. Im Vergleich zu ihren silikatischen Ausgangsgestein, wozu Gneise oder saure magmatische Gesteine gehören können, weisen Rodingite eine Anreicherung von CaO bis über 35 % auf. (de)
- Le rodingiti sono rocce metasomatiche a silicati di calcio; sono rocce a grana fine, di colore grigio, roseo o verdolino, non foliate, generate da una reazione chimica tra le serpentiniti e altre rocce metamorfiche a contatto con esse. (it)
- Rodingit – skała metamorficzna głównie wapniowo-krzemianowa zbudowana z granatów wapniowych (grossular, andradyt) i wapniowych piroksenów (diopsyd), powstała w wyniku niskootemperaturowego metamorfizmu metasomatycznego (zob. → metasomatoza). Rodingity powstałe w wyższych temperaturach (750-800 °C) określane są mianem metarodingitów. Nazwa pochodzi od rzeki Roding w w Nowej Zelandii, opisana w 1911 r. przez P. Marshalla. (pl)
- 羅丁岩（英語：Rodingite）是由鈣鐵榴石、鈣輝石(calcic pyroxene)、符蘇岩(vesuvianite)、綠簾石和方柱石(scapolite)組成的交代變質岩 。 主要產於鎂鐵質岩石靠近蛇紋石化的超鎂鐵質岩石的地方。 當超鎂鐵質岩石被鎂鐵質岩石被蛇紋石化時，所排除的流體副產品含高 pH 值、Ca2+ 和 OH- ，與鎂鐵質岩石接觸後，發生交代變質作用，而造羅丁岩，羅丁岩的礦物組成變化很大，但都具有高鈣、和低矽的特徵。 羅丁岩產出最多的地方是蛇綠岩、蛇紋岩混雜岩、海底橄欖岩和榴輝岩地區中。 羅丁岩是根據在新西蘭，羅丁河出露的頓山蛇綠岩帶的露頭而命名。 (zh)
