(2006)Впервые приводятся детальные геолого-структурная, петрографо-минералогическая и геохимическая характеристики Ондомозерского, Пялочноозерского и Песчаноозерского мафит-ультрамафитовых массивов (Кольский полуостров), данные ...
-
(2006)Анализ древнейшей геологической истории Чешского срединного массива с использованием палеотектонических реконструкций позволяет проводить аналогии с канадской рудной провинцией Атабаска и считать известные гидротермальные ...
-
(2006)The present study deals with rapid, automatic, estimation of some earthquake parameters (location, focal depth, and magnitude) in a region of rather high seismic activity, in quasi-real time, through the analysis of incoming ...
-
(2006)Acceleration records of the Tottori earthquake (6 October 2000), provided by stations of the Digital Strong-Motion Network Kik-Net, show clear evidence of the nonlinearity of soil response at sites located in near-fault ...
-
(2006)В статье по разработанной автором систематике дается описание тектоники структур Восточно-Европейской платформы: Онежского рифтогенного овоида, клинораздвиговых систем: Тимано-Печорской и Вилюйской (Сибирская платформа), ...
-
(2006)The Southern Urals of Russia contain what is arguably one of the best-preserved examples of an arc-continent collision in any Paleozoic orogen. The arc-continent collision history recorded in the rocks of the Southern Urals ...
-
(2006)Scheuchzerite, Na(Mn,Mg)9[VSi9O28 (OH)](OH)3, is a new mineral from the metamorphosed syn-sedimentary exhalative Mn deposit of Fianel, Val Ferrera, Central Alps, Switzerland. It is dedicated to the Swiss naturalist Johann ...
-
(2006)Crystal chemical analysis of various dioctahedral 2:1 phyllosilicates consisting of trans-vacant (tv) and cis-vacant (cv) layers and interstratified cv and tv layers shows that there is compositional control over the ...
-
(2006)The solubility of (i) Au(cr), (ii) mixtures of crystalline Ag2S-Ag3AuS2, and (iii) Ag3AuS2 (uytenbogaardtite)-AgAuS (petrovskaite) was measured at 25 °C, 1 bar, whereas the solubility of AgAuS(cr) was measured at 91-250 ...
-
(2006)Advances in seismic tomography and mantle convection modeling have led to the convincing conclusion of whole-mantle convective flow, so that compositional differences between upper and lower mantle could not have been ...
-
(2006)Phase formation in ternary system of complex Sc, Na and Li phosphates was studied at 950°C and synthesis of new phases of definite composition was carried out. Obtained specimens were investigated with X-ray powder ...
-
(2006)During diagenesis of Jurassic and Cambrian oil source rock shales illite-smectite(-vermiculite) [I-S(-V)] is transformed to illite-tobelite-smectite(-vermiculite) [I-T-S(-V)]. This transformation of S layers to T layers ...
-
(2006)The chemistry and crystal structure of a unique Zn-rich kupletskite: (K1.55Na0.21Rb0.09Sr0.01) ∑1.86 (Na0.82Ca0.18) ∑1.00(Mn4.72Zn1.66Na0.41 Mg0.12Fe0.092+∑7.00 (Ti1.85Nb0.11Hf0.03)∑1.99 (Si7.99Al0.12)∑8.11O26 (OH)4(F0.7 ...
-
(2006)In this communication we present an estimation of the concentration of single substitutional nitrogen atoms (P1 centre) from EPR data in Kokchetav diamonds. We first performed an analysis of local P1 centre concentrations ...
-
(2006)Dehydroxylated Garfield nontronite has been studied using Mössbauer spectroscopy. According to literature, in dehydroxylated Fe3+-rich dioctahedral 2:1 phyllosilicates (celadonites, glauconites and nontronites), the ...
-
(2006)Metamorphic diamonds from the Erzgebirge, Germany have been investigated using synchrotron infrared absorption, Raman scattering, and fluorescence spectroscopy. Infrared absorption features associated with C-C, C-H bonds, ...
-
(2006)Variations of Eu/Eu* ratio in shales from the upper Vendian Kairovo and Shkapovo groups of the Shkapovo-Shikhan depression, the Volga-Ural region, are considered. Shales in the lower part of the Karlin Formation are ...
-
(2006)Organic-walled phytoplankton assemblages from Eocene and Oligocene reference sections of western Kamchatka are analyzed. They are close in taxonomic composition to coeval assemblages of northern Japan and Sakhalin that is ...
-
(2006)Geochronological database considered in the work and characterizing the Anabar collision system in the Northeast Siberian craton includes coordinated results of Sm-Nd and Rb-Sr dating of samples from crustal xenoliths in ...
-
(2006)Individual grains of zircon from the Archean Kostomuksha, North Karelian and Matkalakhta greenstone belts, which are situated respectively in western, northern and eastern Karelia, are studied using the ion microprobe ...
