Almandine, spessartine, grossular, uvarovite, andradite and pyrope are six minerals which are regarded as belonging to the garnet family.
The mineral trains are composed of pyrope and eclogitic garnets, as well as ilmenite.
If F is bounded, then its face lattice is isomorphic to the face lattice of the (m - 1)-dimensional pyrope.
For the most part pyrope does not occur in collectible crystals; nevertheless, in "Pyrope from the Dora-Maira Massif" (Gilla Simon) collectors can learn about a geologically unique occurrence in Italy, and in "The Fiery-Eyed Volcanoes of Bohemia" (Jiri Kourimsky and Jaroslay Hyrsl) there's a sketch of the 2,000-year history of mining Bohemian gem pyropes which originate in Tertiary-age volcanic rocks.
The first of these is pyrope garnet, the name coming from the Greek word for fiery.
This property is host to pyrope beach sands dominated by favourable G10 pyrope mineral chemistry.
Figure 9 shows a theoretical background that has been fitted to a spectrum of pyrope garnet at 2.
Deep drilling will be performed at other magnetic targets, some of which have produced significant indicator minerals, including a pyrope garnet at one locality and chrome spinel from all the anomalies.
Kimberlite is a host rock to diamonds, but not a source rock: Kimberlite indicator minerals consist of pyrope and eclogitic garnets, magnesian ilmenite, chromite, chorine diopside, forsteritic olivine and diamond and the presence of these minerals is used to determine the proximity of diamond-bearing kimberlites.
A soil geochemical sample collected over one dyke yielded significant pyrope, chrome diopside and olivine and minor amounts of indicator minerals were recovered from small stream sediment samples.
