The snowy Polar Urals end of june [photo: Maurice de Graaf]
The Polar Ural is the most northern part of the Ural. The term 'Polar Ural'
occurs on many mineral labels incorrectly. Officially the Polar Ural, or
Polyarni Ural is everything north of 65°N. The area just south of 65°,
where many alpine mineral localities are found, is called the Pripolyarni Ural,
or the Prepolar Ural. Both areas will be discussed in this chapter. I will use
the English 'Polar Ural' on this page to denote both area's.
The Polar Ural is the highest part of the Ural range, but still most mountains
are hilly. There are occasional rock faces in between. It is not so much the
mountains that make this area uninhabitable, but the climate and the lack of
roads. In the summer of 2003 I flew over the Polar Ural twice and while most of
northern Russia was free of snow and ice, the Polar Ural was still white, as the
picture above shows.
alpine paragenese
Many localities in the Polar Ural are of the so called alpine paragenese. So
this is the place to explain a little about alpine minerals. Alpine mineral
formation is a special kind of hydrothermal mineral formation. The
buildingblocks of the minerals precipitate from hot water, often under pressure.
Normally this water is derived from nearby magma and flows through cracks in the
rock. This yields the classic vein deposits, the type of many ore
deposits.
The Alpine Range is a large metamorphic zone. Italy moves north and the rocks
inbetween are comressed. This causes the mountains to be formed. The rocks are
compressed and altered metamorphically. A granite can for instance become a
gneiss. During this compression all kinds of crack occur in the rock, forming
cavities, or alpine clefts. Water present in the rock or meteoric water is
heated up by the pressure and starts circulating through the rock, picking up
all kinds of buildingstones from that rock. When the water reaches a cleft
crystals can freely grow. One of the most common building blocks is silica, so
quartz is present in almost all alpine clefts. The rest of the paragenese
depends largely on the type of rock in which the cleft is found. Gneiss will
yield a different paragenese than for instance amphibolite.
The alpine paragenese was first studied in the Alps, hence it's name. Later
similar conditions where found elsewhere. The best known alpine localities
outside the Alps lay in the Polar Urals.

The Kozhim river basin is mentioned as a Lazulite locality. The Lazulite occurrence is over 20km long and it is quite possible that other lazulite localities mentioned on this page are within this basin.
A well known locality for Anatase. Strangely not much more is known about this locality by me.

Marun Keu is not really a locality, but a complex, covering 100 km2
along the western edge of the main suture zone of the Uralian orogeny. Within the
Marun Keu occur outcrops of high pressure eklogite rocks. The eklogites
where formed in a subduction zone, but the reaction was not complete resulting
in the formation of hydrothermal quartz-phengite-rutile veins.

Mun Hambo is best known as type locality for Tsaregorodsevite. In reality Mun Hambo, or Man Khambo is a range in which the true typelocality, Mount Yaruta is situated. So not a true locality!
I have doubts with this locality. Mount Neroika is a prominent landmark in the area. I think therefore that the minerals stated to be from Neroika are in reality from nearby Dodo. Nevertheless a list of minerals I encountered from 'Neroika'

Rai Iz is a well known name and a true Polyarni Ural locality. The place gained
fame for it's great rubies. Rai-Iz itself is an ultrabasic massif, located
located between the settlements Polyarny and Charp, about 50 kilometers north of
the Arctic circle. Rai-Iz is an Dunite-Harzburgite massiv. Inside this complex
are metasomatite veins in which the rubies occur.Within the 300 x 100 meter
small Rai Iz massif are about ten such localities. Chromite from the massif is
the donor of the chromium in the ruby. The best known ruby locality within
Rai-Iz is called Rubinovoye.
The Karovoye deposit and Nyrdvomenshor are part of the Rai-Iz complex and known as a Jadeite/Nephrite localities.
