Rodingite
is a somewhat rare mixture of minerals. The name Rodingite
was first used by P. Marshall in 1911 to describe certain
dike rocks from Roding River, Dun Mountain area, Nelson,
New Zealand, consisting of Grossular Garnet along with
other calcium silicate minerals such as Vesuvianite,
Prehnite, Wollastonite, Diopside and hydrogrossular.
Since then the name Rodingite has been applied to garnetized
gabbros and dolerites by various authors. Grange (1927),
Miles (1950), and Bloxam (1954) have described garnetized
gabbros from different parts of the world. A recent
limited find of Rodingite in Kazakhstan has produced
very attractive material consisting of Grossular Garnet
(white) and the manganese rich variety of Vesuvianite
(purple) as pictured above.
