- The Kola Peninsula in northwestern Russia is truely an amazing mineral
locality. This large and important region has produced over three hundred
different mineral species and is the type locality for over a hundred minerals.
The rich bonanza is the result of several unique igneous intrusions that
occured from 3 billion years ago to 360 million years ago. Some were rich
in alkali metals, especially sodium, and poor in silica and aluminum. Pegmatitic
rocks produced from these unique intrusions are call agpaitic pegmatites
and are found scattered all around the world. The agpaitic pegmatites of
the Kola Peninsula as well as those of Narsarsuk,
Greenland;
Langesundfjord,
Norway and especially Mont
Saint-Hilaire, Quebec, Canada are by far the most famous. In addition
to agpaitic pegmatites, intrusions of syenites and nepheline syenites,
carbonatites, amazonic rand-pegmatites, peralkaline granites and metamorphism
add to the mineral assortment with another cast of unique minerals.
In addition to the unusual chemistry of high alkali metal content and
low silica and aluminum content; there is also unusually high concentrations
of titanium, zirconium, phosphorous, manganese, strontium, zinc, lead,
uranium, barium and especially rare earth metals such as yttrium, niobium,
cerium, lanthanum, cesium, ytterbium and neodymium. Many of the new minerals
found here are typically sodium titanium silicates. By far the greatest
number of unique minerals from the Kola Peninsula are silicates. But, unique
carbonates, oxides and phosphates are also well represented. In the table
below, minerals that were first discovered from the Kola Peninsula (called
the mineral's type locality) are in bold. The list below is quite
extensive, but still not close to a complete list of all the minerals found
here. The list of minerals includes those minerals that were discovered
here as well as those that have been given world wide attention from this
locality.
The Kola Peninsula sits almost completely above the arctic circle, south
of the Barents Sea. Murmansk is the only large city in the Russian portion
of what was traditional Lapland. The Khibiny Mountains surrounded by tundra
in the center of the peninsula was the result of the mineralogically rich
agpaitic alkali intrusions. Glacial erosion helped uncover the pegmatitic
rocks which comprise the khibiny and Lovozero massifs. As a testament to
this wonderful mineral location, many of the minerals discovered here were
named in honor of these localities. Can you find them below?
