It is a major mineral component of eclogite along with pyrope garnet and also occurs in blueschist facies and UHP ( ultrahigh-pressure ) metamorphic rocks.
32.
The different species are pyrope, almandine, spessartine, grossular ( varieties of which are hessonite or cinnamon-stone and tsavorite ), uvarovite and andradite.
33.
In chemical composition it may be considered as essentially an isomorphous mixture of pyrope and almandine, in the proportion of two parts pyrope to one part almandine.

Some minerals are thermochromic as well; for example some chromium-rich pyropes, normally reddish-purplish, become green when heated to about 80 �C.
36.
Secondary ( metamorphic ) minerals include chlorite, amphibole, sodic plagioclase, quartz, iron oxides and rarely phlogopite, baddeleyite, and pyrope or hydrogrossular garnet.

Pyrope, you claim that : " " You started well by backing up your point of view, but you never should have let it get personal.
38.
Minor minerals and mineral groups in peridotite include plagioclase, spinel ( commonly the mineral chromite ), garnet ( especially the mineral pyrope ), amphibole, and phlogopite.
39.
Garnets tend to be less strongly coloured than other silicate minerals in thin section, although pyrope may show a pale pinkish-purple hue in plane-polarized light.

Pyrope states that " " Your assertion that Arcayne's " " okey-doke " " comment was unprovoked is laughable, by the way.
