Two models of prediction of copper-polymetallic resources district Dalaymyao (Inner Mongolia, China) (Федеральное государственное бюджетное образовательное учреждение высшего образования «Московский государственный университет им. М. В. Ломоносова», 2011)Weak geological knowledge Dalaymyao area and a large resource potential of the copper-polymetallic ore casts doubt on an adequate assessment of mineral content using traditional research methods. The authors of this article ...
-
(2003)The distribution of clay-mineral abundances on the inner continental shelves of the East Siberian and western Chukchi Seas well confirms to the dominant regional circulation pattern. The clay mineralogical analysis distinctly ...
-
(2003)Two neoceratopsians, Lamaceratops tereschenkoi gen. et sp. nov. and Platyceratops tatarinovi gen. ct sp. nov., from the Barun Goyot Formation (?Lower Santonian, Upper Cretaceous) of the Khulsan and Khermiin Tsav localities ...
-
(2003)Two new species of Mesosolva Hong, 1983 and Archirhagio Rohd., 1938 are described and the taxonomic position of these genera is reviewed. The age of the Daohugou Formation (Inner Mongolia, China) is discussed.
-
(2002)We present major and trace-element, oxygen isotope, textural, and structural data for carbonates and related phases in the SNC meteorite ALH84001. These data document the existence of at least two distinct carbonate ...
-
(2001)The present paper describes two compound chondrules labelled panda and chevron, discovered in the Baszkówka meteorite. Optical microscope, electron microscope and electron microprobe studies revealed an unusual mineral ...
-
(2003)The abundance and morphology of microdiamond in dolomite marble from Kumdy-kol in the Kokchetav Massif, are unusual; a previous study estimated the maximum content of diamonds in dolomite marble to be about 2700 carat ...
-
(1997)A combined solution for the two major terrestrial lead paradoxes has been sought. These are the ‘future’ paradox (upper crustal and upper mantle Pb isotope compositions plot in the future field in 207Pb/204Pb vs. 206Pb/204Pb ...
-
(1989)The sudden, rapid advance of the snouts of certain mountain galciers has long been familiar. Systematic study of these phenomena began in 1956, with the catastrophic advance of the snout of the Muldrow Glacier in Alaska. ...
-
(2001)In the pre-Upper Carboniferous Malá Fatra Mts. metamophic complex in the Western Carpathians, banded amphibolites and amphibole gneisses include Grt-Cpx-Hbl-Pl metabasites of two types. Type I comprises massive coarse-grained ...
-
(1989)Comparison of rocks studied shows that the largest differences between ongonites and elvans from different granite associations are those in the oxides of iron, calcium and phosphorus. The ongonite associated with plumasitic ...
-
(2000)Two Type B refractory inclusions, consisting mainly of melilite, fassaite and spinel +/- anorthite, were found in the anomalous Ningqiang carbonaceous chondrite. The composition of melilite varies from #9k4-15 near the ...
-
(2005)The occurrences of natural coexisting feldspars including hyalophane and also celsian delineate two-, three- and possibly four-phase fields in the system BaAl2Si2O8-CaAl2Si2O8-NaAlSi3O8-KAlSi3O8. Hyalophane occurs with ...
-
(2003)We present 2-D simulations of convection in the Earth's mantle with temperature and damage-dependent viscosity in a basally heated system. The equation governing the temporal evolution of damage includes a source term for ...
-
(2002)Interpretation of magnetotelluric (MT) data for three-dimensional (3-D) regional conductivity structures remains uncommon, and two-dimensional (2-D) models are often considered an adequate approach. In this paper we examine ...
