HM3-U5VKhoharite : Mg3Fe3+2(SiO4)3

Tomtor Massif, Polar Yakutia, Sakha Republic, Eastern-Siberian Region, Russia

Khoharite as a hypothetical end member of the Garnet group with formula Mg3Fe3+2[SiO4]3 was proposed by L.L. Fermor in 1926. In addition Khohar in India, the presence of this component was observed in garnets from kimberlites of Jagersfontein (South Africa), but nowhere its content did not exceed 20 at.%.
This transparent rhombododecahedral crystal of pale pink color, visually indistinguishable from the almandine from gneisses, were found in heavy concentrates from the rich, redeposited within a lake coastal vawe-surf zone ores of Tomtor. Pyralspite appearance of this garnet is amazing does not agree with its ugrandite composition. First of all, it absolutely does not contains aluminum. The contents Khogarite end member here is 49.6 at.% and exceeds the following by weight of Andradite end member (42.6 at.%). So thit is the first record of garnet in the world with a predominance of Khoharite end member - the Khoharite itself, I beg to love and favor it. Unfortunately, this crystal is the first and only known at the moment.
Analytical data are available at the daughter photo.

Koashva Open Pit, Koashva Mt, Khibiny Massif, Murmanskaya Oblast', Northern Region, Russia

Field of View: 11 mm

Two sections of isometric crystals of transparent and colorless Arctite (red arrowed in the center) within Natrolite matrix. One more, the smaller complete Arctite crystal is visible at the right side of the photo - it is under surface of transparent Natrolite grain. Associating minerals are brown Lamprophyllite plates (at the left) and greenish-black prismes of Aegirine (at the right).
Arctite has strong scheelite-like blue fluorescention under LW UV.
