The Severnyi Ural is the Northern Ural. The area between Nizhne Tagil and the Pripolar Ural. Politically this area is part of the Permskaya oblast in the west and the Sverdlovskaya oblast in the east.
A chromium deposit near Laki in the Permskaya oblast. It consists of ultrabasic rocks and is very similar to the better known Saranovskoye mine. In fact Biserskoye is located only 12 kilometers south of Saranovskoye. In the 19th century this mine was much better known than Saranovskoye. In fact it is the type locality Shuiskite is Biserskoye and not Saranovskoye! Clinochlore occurs here in the variety Kämmererite. In the 19th century the mine was known as Biserkii Zavod.

Krasnoturinsk is a name of a town in the so called Auerbach-Turin ore field. In this ore field are numerous iron and copper skarns located. The country rock consists of different kinds of volcanic-sedimentary rocks with limestone lenses of the Tagil-Magnitogorsk greenstone belt. The sediments are Upper Silurian to lower Devonian and have a total thickness of over 3000 meters. These sediments where intruded by the Central Auerbach intrusion and several satellites. The Auerbach intrusion consists mainly of granodiorite. At the northwest side of the intrusion formed about 15 copper rich skarn ore bodies. The largest are Frolovskoye, Nikitin, Novofrolovskoye, Nikolo-Podgora, Bashmakovskoye, Bogoslovskoye and Vadimo-Aleksander deposits. (See below for more about Novofrolovskoye)
In the southwest of the intrusion lay iron rich skarns.

The Kytlym massif is a dunite intrusion, located about 400km north of Nizhne Tagil. The massif consists of five large blocks, named Kosva, Konzhankov, Sukhogorsk, Serebryansk and Valentorsk. The Valentorsk and Sukhogorsk blocks consist mainly of Gabbronorite and Clinopyroxenite. The Srebryansk block consists of Gabbro and magmatic breccia. The Konzhakov and Kosva blocks consist of Dunite, Clinopyroxenite and Gabbro.

Marsyat is a paleogene sedimentary manganese deposit on the eastern slope of the Severnyi Ural.
A skarn deposit near the town of Krasnoturinsk. This hercynian skarn is located in the proterozoic Tagil-Magnitogorsk greenstone belt. See Krasnoturinsk, above, for a more detailed description of the geology.

Peschansk is a magnetite-calc skarn, about 10km south of Krasnoturinsk. The skarn is formed by an intrusion of diorite in limestone. The diorite is the Peschansk diorite massif, which is part of the larger Auerbakh intrusive complex. The limestone is devonian sediment and it is covered with vulcanogenic sediments. Of course the limestone altered to marble and the volcanosediments to hornblende porphyrites.
Polunochnoe is a Paleogene sedimentary manganese deposit on the eastern slopes of the Severnyi Ural.
Saranovskoye is a Caledonian ultrabasic intrusion consisting of gabbro and gabbronorite in precambrean schist and quartzite. There are three major chromite orebodies and several smaller ones as well as diabase dikes. Mineralogically the chromite ore contains pockets of calcite and chromium minerals as well as some PGM minerals. The well known chrom titanites come from the diabase dikes .

I would like a confirmation on Crocoite. I had it as 'doubtfull' in my database, but Burlakov mentions galena, with which it would make sense afterall.

Serovsk is a nickel-silicate deposit. This deposit was formed by weathering of serpentine rocks

Solikamsk is surprisingly little known in the west. It is located on the western outskirts of the Ural north of Perm. "Solikamsk" actually means "salt of the Kama". No surprise the town was established as salt mining town in 1430. It was even briefly the capital of the Ural. The town's heraldy refects a well where the salt brine is winched up. The salt is currently mainly of interest for high magnesium content. The Solikamsk Magnesium Works produce the metal here. Other metals present in the brine are ceasium and rubidium. So far I found only the Verkhnekamskoye mine, but there are definitely more works. Nearby villages also have saltmines, such as Berezniki, Zarazina and Kruggly Rudnik.
Geologically the salt is of early permian age.
