-
(2006)The study of the chemical behavior of highly siderophile elements, including platinum group metals (PGM), is of great theoretical and practical significance for understanding the early differentiation of the Earth, mantle ...
-
(2006)The problem of endogenic carbonification of rocks and related ore mineralization is topical for many reasons. The possibility of accumulation and transfer of various metals with reduced carbon-rich fluids has been proved. ...
-
(2006)The influence of hydrogen is considered in many geological processes, and the special role of hydrogen is emphasized in deep geodynamics in the ascent of mantle plumes. Some models of diamond formation also assume an ...
-
(2006)Picroilmenite of kimberlitic rocks is among the major typomorphic minerals widely used in geological prospecting. Therefore, the elucidation of compositional differences between ilmenites from various fields of the Yakutian ...
-
(2006)The Muya structural zone, one of the regions with a high potential of gold mineralization, incorporates more than 300 gold occurrences and deposits. Ore occurrences of the gold–quartz formation are most widespread in this ...
-
(2006)The crustal structure in the Baltic Shield is determined by a system of geological blocks, which formed at different evolutionary stages of this largest stable Precambrian domain. Cratonization of the Archean Karelian, ...
-
(2006)Hydrophysical measurements in the Romanche Fracture Zone carried out in October 2005 were compared to the data of measurements in 1991. As a result, warming by 0.01°C was found in the core of North Atlantic Deep Water ...
-
(2006)The Earth’s crust beneath the Atlantic Ocean has a heterogeneous tectonic structure. The northern (Arctic and subarctic) region is characterized by a particularly specific structure. The region is located between two ...
-
(2006)Regional structural features of the Yenisei Ridge are traditionally displayed as a NW-trending linear system of tectonic sheets that are thrust over one another and separated by faults where collision of blocks occurs. As ...
-
(2006)An algorithm for researching a quantitative index of seismic activity (QISA) of faults. The index provided a ranking of the faults by degrees of their recent activity on the real time scale and enabled analyses of contributions ...
-
PINE NEEDLES AS A BIOMONITOR FOR ESTIMATION OF THE REGIONAL-SCALE DISTRIBUTION OF ORGANIC POLLUTANTS (2006)Classic methods of the monitoring of pollutants to determine areas of their distribution from the sources have many limitations. The direct regular sampling of atmospheric air with a required number of sites in the study ...
-
(2006)The aim of this work is to show that the formation of the unique Sukhoi Log deposit and other smaller gold ore deposits of the Bodaibo area was related to a series of geological and geodynamic events. Each of these events ...
-
(2006)The recognition of the Vendian as a terminal Precambrian system and the biostratigraphic subdivision of its upper part were an important step in constructing the general chronostratigraphic scale for the Upper Proterozoic ...
-
(2006)Paragenetic associations with diamond in kimberlites can be subdivided into three main types: (1) inclusions of various minerals in diamond crystals, (2) mineral intergrowths with diamonds, and (3) xenoliths of diamondiferous ...
-
(2006)Essential problems of the oldest geological stage in the Earth’s history (Hadean Geon) marked by formation of geospheres and their transformation during initial interaction remain highly debatable still today because of ...
-
(2006)Solid bituminous matter (SBM) typically occurs in the late hydrothermal assemblages of pegmatites of the Khibiny and Lovozero massifs, being confined to a microporous framework Ti-, Nb-, and Zr-silicates, which are sorbents ...
-
(2006)Newly obtained data highlight strong geological and geochemical differences between Late Cretaceous-Paleogene and Eocene-Middle Miocene volcanic rocks in the southern Korean Peninsula. The rocks are spatially separated and ...
-
(2006)Phengite, K(Mg,Fe)0.5Al1.5[Si3.5Al0.5O10](OH)2, is a dioctahedral mica intermediate between muscovite and aluminoceladonite in the nomenclature. Divalent cations, mainly Mg2+ and Fe2+, substitute for Al in the octahedral ...
-
(2006)Relationships between noble-metal and oxide-sulfide mineralization during the origin of the Volkovsky gabbroic pluton are discussed on the basis of geochemical data and thermodynamic calculations. The basaltic magma initially ...
-
(2006)This paper presents the results of a study of the Vesely carbonatite occurrence in a new carbonatite-bearing area of northern Transbaikalia. The REE patterns, oxygen and carbon isotope compositions of carbonates and ...
