Eclogites are fine-grained rocks consisting of garnet porphyroblasts set in a matrix of omphacite (25%), amphibole (hornblende or barroisite) (20%), plagioclase and zoisite
; rutile often rimmed by titanite occurs as the main accessory mineral phase, phengite is quite rare whereas quartz is nearly absent.
It's a gem-quality zoisite
ranging in colour from deep blue to burgundy red through violet and purple and several gem hunters have claimed they were the first to find it.
Wilson and partners are exploring the possibility of extracting a mineral called zoisite
from the mountain, which may, or may not, have a bizarre application.
UBAIDULLAH QADRI: Pakistan has enormous wealth of expensive gems such as ruby, emerald, tourmaline, garnet, topaz, peridot, aquamarine, spinel, pargasite, diopside, moonstone, pink topaz, sapphire, zircon, feldspar, agate, serpentine jade, epidote, pink beryl (morganite), purple beryl, sphene, zoisite
, lapis lazuli, turquoise, and kunzite etc.
Of course, the blues (and purple-blues, and some yellows) are tanzanite zoisite
, and the greens are "tsavorite" grossular and chromium-rich diopside.
The metabasic rocks include common amphibolites and zoisite
and rutile-rich amphibolites.
The REE in clastic sediments are concentrated in detrital accessory minerals, mainly phosphates (notably monazite and apatite for LREE and xenotime for HREE), minor silicates (notably allanite, titanate, and zoisite
for LREE, garnet and zircon for HREE), and adsorbed to clays (especially HREE).
The gem that put Tanzania on the world precious stone map was its namesake tanzanite, a blue zoisite
found solely near the town of Arusha in northern Tanzania.

), society Long U disuse
That's why you'll find Zababa, Zincenite, Zippeite, Zoisite
, Zoubekite, Zunyite, Zussmanite, Zvyagintsevite, Zweiselite in the Z section of the alphabet.
Other minor constituents of marbles can include fluorite, apatite, brucite, laumontite, olivine, scheelite, spinel, zoisite
, and magnetite.
Primary ores, assigned to the gold-sulphide formation, are represented by metasomatically altered rocks composed of carbonates, quartz, micas, chlorite and zoisite
. The discovery of Olimpiadninskoe is one of the proofs for the high potential of finding further deposits in the Yenisei goldfield.
