(2001)The Re–Os data on Archean komatiites from the Kostomuksha greenstone belt in the Baltic Shield are presented. This greenstone belt has been previously interpreted to represent a former oceanic plateau formed by the emplacement ...
-
(2004)The U-Pb system was examined in minerals of the main rock types from the Ladoga area: early- and synorogenic enderbites, diorites, syn- and late-orogenic K-granites, the leucosomes of migmatites, and their host garnet-cprdierite ...
-
(2004)An unusual association of platinum-group minerals (PGM) is observed in a chromitite layer of the Mount Bol' shaya Varaka deposit, Imandra layered complex, Kola Peninsula, Russia. The PGM typically occur as cluster-like. ...

(2004)Eclogites of Archean (2720± 8 Ma) and Proterozoic (2416.1± 1.3 Ma) age were found in the Belomorian Mobile Belt of the Baltic Shield near the village of Gridino in Karelia. The unique Archean eclogites described in this ...
-
(2004)Regional seismic tomography provides valuable information on the structure of shields, thereby gaining insight to the formation and stabilization of old continents. Fennoscandia (known as the Baltic Shield for its exposed ...

(2004)The Early Paleoproterozoic (2.46-2.36 Ga) Belomorian drusite (coronite) complex was addressed to for the first time in discussing the geology, petrology, and genesis of dispersed intrusive mafic-ultramafic magmatism that ...
-
(2003)Assessment of contributions from shallow lithosphere to teleseismic wave front distortion is a prerequisite for high-resolution regional teleseismic tomography. Several methods have been proposed in the past for the ...
-
(2005)New analyses of highly siderophile elements (HSE; Re, Os, Ir, Ru, Pt, and Pd) obtained by Carius tube digestion isotope dilution inductively coupled plasma mass-spectrometry (ID-ICPMS) technique are reported for 187Os-enriched ...
-
(2004)Information on the structure of the upper mantle comes from two main sources. Regional seismic studies provide indirect information on large portions of the lithosphere, and mantle xenoliths provide direct information about ...
