Alkali-Metasomatites from the Polar Urals.

Udoratina, Oxana V (PANGAEA, 2001-10-13)

Rare-metal alkali (quartz-feldspathic) metasomatites are considered in terms of their geologic position, structure, and composition. Their petrochemical and geochemical characteristics are given. In the Polar Urals, the ...

Chemical and mineralogical investigations of the sediments of the Barents and White Seas (in Russian).

Gorshkova, Tatyana I (PANGAEA, 1931-06-06)

Fe-Mn aggregates are presented in the paper where flat and round concretions (from several mm to 10-12 cm in diameter) and Fe-Mn crusts on bivalves and polychaete tubes with different Fe-Mn ratio are described.

Coarse ice-rafted debris in the bottom sediments of the Kara Sea.

Lisitzin, Alexander P; Kharin, Gennady S; Chernysheva, E A (PANGAEA, 2004-07-12)

Composition and distribution.of ice-rafted coarse debris from the Kara Sea bottom were investigated. This material was obtained on 42 stations in Cruise 49 of R/V Dmitry Mendeleev by Sigsby trawls, box corers, grabs, and ...

Early Cretaceous volcanic rocks and Early Cenozoic extrusions of Cape Mary, Schmidt Peninsula, North Sakhalin: Geochemical study.

Simanenko, V P; Rasskazov, S V; Yasnygina, T A; Malinovsky, A I; Chashchin, A A (PANGAEA, 2007-11-05)

Early Cretaceous volcanic rocks of the Mariisky sequence and Early Cenozoic extrusive-vent rocks of the Mary Cape are exposed at the most northwest of the Schmidt Peninsula, North Sakhalin. In chemical composition, all the ...

Geochemical evolution of Late Eocene-Oligocene magmatism on the Shmidt Peninsula (Northern Sakhalin).

Rasskazov, S V; Simanenko, V P; Malinovsky, A I; Yasnygina, T A (PANGAEA, 2007-09-29)

Middle Cenozoic evolution of magmatism in the Schmidt Peninsula between 37 and 25 Ma began with eruptions of subalkaline and moderately alkaline andesite, latite, trachyandesite, and trachyrhyolite lavas and ended with ...

Holocene hydrological variability of Lake Ladoga, northwest Russia, as inferred from diatom oxygen isotopes.

Kostrova, Svetlana; Meyer, Hanno; Bailey, Hannah; Ludikova, Anna V; Gromig, Raphael; Kuhn, Gerhard; Shibaev, Yu A; Kozachek, Anna; Ekaykin, Alexey; Chapligin, Bernhard (PANGAEA, 2019-03-15)

This article presents a new comprehensive assessment of the Holocene hydrological variability of Lake Ladoga, northwest Russia. The reconstruction is based on oxygen isotopes of lacustrine diatom silica (δ18O diatom) ...

Metabasite basement of the Voikar Island Arc in the Polar Urals.

Remizov, Dmitry N (PANGAEA, 2011-02-12)

High-pressure/low-temperature metabasites occupy a definite geological position within the structure of the Polar Urals and have a very important bearing on the understanding of the early history of the Ural Mountains. ...

Nature of ferromanganese formations of the Laptev Sea.

Kalyagin, A N; Tishchenko, P Ya; Gukov, Aleksander Yu; Volkova, T L; Kurilenko, L N; Chichkin, R V (PANGAEA, 2001-05-30)

In sediments of the Laptev Sea unknown earlier ferromanganese manifestations have been found. On the basis of structural-textural external signs they have been divided to five groups: 1) tube- and spindle-shaped pseudomorphs ...
