Chukotka is the most northwestern part of Russia, close to the Bering Strait. The majority of Chukotka is inhabited by the local Chukots. A nomadic tribe who live mainly of reindeer herding. Apart from these nomadic people there a few small settlements.

     Analcime

Anmandykansky massif

Located in the basin of the Omolon river. I'm not sure about the exact locality, but the Omolon mainly flows through Chukotka, so I put it here.

Chetigun river

Although Chetigun river is frequently mentioned as Axinite locality, I believe it is the same locality as Pribrezhnoye, located near the mouth of the Chetigun.

Iul'tin

geology
Iul'tin is a hydrothermal tin-tungsten deposit in the Ekeotap Khrebet. The deposit consists of  three groups of sedimentary-metamorphic rocks. Lower Carboniferous crystalline schists and limestones, Upper Permian shales, sandstones and siltstones of the Iul'tin group and Triassic shales siltstones and sandstones of the Amguem group. In this lay Triassicgabbro intrusions as well as Cretacous granodiorites of the Pravo-Iul'tin massif and Upper Cretaceous granite of the Iul'tin massif. The Iul'tin mine was opened in 1954 and extended in 1959.

Karal'veem deposit

The Karal'veem deposit became most of all known for single find of a specimen with multiple 1cm gold crystals.

Palyansk
(Polyansk)

geology
The Palyansk deposit is located in Upper Triassic terrigenous sediments (sandstones, siltstones and shales). The shales contain siderite and organic matter. The west side of the deposit is covered with Cretaceous volcanogenic rocks and the sediments are cut by various dykes of lamprophyre, granodiorite and aplite, as well as Quartz-carbonate veins.

Plamennoye deposit

geology
The Plamennoye deposit is located at the edge of the Okhotsk-Chukotka volcanic belt. The deposit consists of various lower Cretaceous volcanic rocks, such as rhyolites and tuffs. These are cut by subvolcanic granitoids,  andesites and late Cretaceous diorites. The rocks are subsequently folded and hydrothermally altered.

Pribrezhnoye

geology
The Pribrezhnoye deposit is a skarn located near the mouth of the Chetigun river. The Quartz occurs here as green quartz because of Actinolite inclusions. Japanese twins are also known from here.

So far I could not find any references of this locality. I have a Ferro-Axinite from this locality in my collection, which looks similar to the Chetigun material.

Tenkergyn
(Volchye)

Tenkergyn is located at the northern shore of the Chukot sea just east of Mys Schmidta. Tenkergyn is greisen deposit well known for it's large orange scheelite crystals. In some older publications Tenkergyn is known as the Volchye deposit.
