Associations with chromite in the district include greenish yellow serpentine, stichtite, uvarovite and transparent gray spherules of prehnite.
Uraninite, however, was noted in samples from Big Creek associated with quartz, uvarovite
Small chromitite bodies near Brassey Hill contain uvarovite
, native copper and a varied assemblage of platinum-group minerals (Carthew and Bellairs, 1988; Peck, 1990; Peck and Keays, 1990).
Minerals from the Urals are also comprehensively represented, including ferroaxinite from Puiva, alexandrite and emeralds from the Malyshevo pits, uvarovite
from the Saranovskoye deposit, and even the famous Urals malachite from Gumeshki and Vysokogorskoye.
Jaroslav Hyrsl (Heverova 222, 280 00 Kolin 4, Czech Republic) did show me a new development from the Sarany, Urals, locality for uvarovite
on chromite (these microcrystalline specimens also continue abundant, by the way).
Some fifty years later, Dresser and Denis (1949) remarked that "the dump at the Orford nickel mine has long been a place of interest for mineralogists on account of the excellent specimens of the relatively rare mineral millerite, and also of uvarovite [grossular] and diopside, that may be collected there." Today, more than a century after mining ceased, the locality continues to be an active mineral collecting site, still producing specimens which are often superior to those in old collections.
For many years the green garnet from the Orford nickel mine has been incorrectly called "uvarovite." In the earliest references it was referred to simply as "chrome garnet" (Hunt, 1863a; Willimot, 1882) based on Hunt's analysis which showed Al>CR.
on chromite from Sarany, Urals, seems capable after all of occasionally forming macroscopic crystals; a couple of the Syntaxis thumbnails have well individualized, half emedded, bright green 2-mm dodecahedrons.
Many genera of the Drymadusini (as well as the non-Drymadusini Gampsocleis and Uvarovites
) possess a prosternum with spines (see Rentz & Colless 1990, characters, state 1; also inDelodusa, own observations).
