-
(2006)This paper reports newly obtained data on the mineralogy, geochemistry, and predicted reserves of the Shaumyan gold-base metal deposit in southern Armenia and the Kharvana occurrence of ore mineralization in northwestern ...
-
(2006)Oxygen fugacity (fO2) in the Earth's mantle has a bearing on the problems of the chemical differentiation of the Earth's materials and formation of the chemical and phase state of its shells. This paper addresses some ...
-
(2006)Annite is an iron-rich trioctahedral mica close in composition to the hypothetical end-member KFe3[Si3AlO10](OH)2. Annite with an ideal composition is known only as a synthetic compound. Natural annites may approach the ...
-
(2006)We investigated the evolution of the southwestern wall of the Baikal Rift Zone (BRZ) based on the seismic structure of the sedimentary cover beneath Lake Khubsugul (Mongolia), a marginal member of the BRZ. The Khubsugul ...
-
(2006)The coastal regions of oceans and seas are regions of high biological productivity, where the largest amounts of autochthonous biogenic compounds, HC inclusive, are formed. In addition, these regions are most subjected to ...
-
(2006)Generation of geomagnetic field is related to dynamo processes in the earth’s liquid core. It is one of the basic problems of geophysics. The geomagnetic field can be generated by both large-scale and small-scale flows. ...
-
(2006)The velocity and acceleration of the North Magnetic Pole (NMP) motion has been increasing sharply since the 1970s and has almost doubled (up to 46 km/yr) in the last 30 yr [1]. During the same period, the velocity of the ...
-
(2006)The necessity of eliminating debris from a granite quarry has awakened an interest in applications of by-products, called “marginal arids”, in different fields, like construction and foundations for roadways, restoration, ...
-
(2006)The subsequent special investigations provided new insights into the mineralogy of PGE and Au in ferruginous quartzites of the KMA. We studied the mode of occurrence of noble metals in compositionally different ferruginous ...
-
(2006)Many natural processes are described by nonlinear parabolic equations of the thermal conductivity equation type, in which the coefficient of the medium is a function of the value sought. Although the class of these equations ...
-
(2006)Oil-and-gas (hereafter, petroleum) fields are in the category of hardly recoverable deposits. If the oil viscosity exceeds 150 cP, the difficulty of the development of such fields increases significantly. At present, there ...
-
(2006)Relations between mineralization and magmatic rocks and sources of ore-forming fluids are presently among the most important problems in endogenous ore formation. Geochemical methods provide a valuable insight into these ...
-
(2006)Three ophiolite complexes of different ages and paleotectonic settings were recognized at the Kamchatsky Mys Peninsula, eastern Kamchatka. Their age was determined from geological data and the microfaunal assemblage of the ...
-
(2006)It is well known that earthquake recurrence plots are well described by the exponential function N (k) = A0 · , where A0 is the seismic activity reduced to surface and time units; k = is the energy class; and γ is the angle ...
-
(2006)Deep low-permeability clay layers are considered as suitable environments for disposal of high-level radioactive waste. In Belgium, the Boom Clay is the reference host formation and the Ypresian Clay an alternative host ...
-
(2006)This paper presents the first data on the systematics of rare earth elements (REE), Th, Hf, Sc, Co, Cr, and Ni and the Nd model ages of fine-grained aluminosilicate clastic rocks of the Serebryanka and Sylvitsa groups of ...
-
(2006)The investigation of primary inclusions in natural diamonds is the main source of information on the environment of diamond formation. It is usually assumed that inclusions trapped during diamond crystallization did not ...
-
(2006)The available geological, geochronological, geochemical, and isotopic data furnish evidence that the Paleoproterozoic protoliths of metavolcanic rocks in the central Aldan Shield were formed within a geodynamic system of ...
-
(2006)Miserite is an infrequent alkali Ca-silicate with two types of silicate radicals. The crystal structure of this mineral from carbonatites of the Kipawa Lake deposit, Quebec, Canada. This work, based on the photo method, ...
-
(2006)This paper presents results of zircon dating of xenoliths from the Udachnaya Pipe. Mafic two-pyroxene garnet granulites (samples uk1 and uk2), mafic amphibole-bearing garnet granulite (uk11), and intermediate garnet granulite ...
