-
(1989)A whole series of observations indicates that intramineralization transformations have an important effect on ore emplacement, but suitable methods of identifying them and estimating their scale have not yet been adequately ...
-
(1999)The main features of the geology and petrology of anorthosite-rapakivi granite complexes (ARGC) are discussed, using the Proterozoic (1.76-1.5 Ga) granite massifs of the Baltic and Ukrainian shields as the examples. According ...
-
(2004)Synthesis of petrological, geochemical, and isotopic data on volcanic rocks and a related suite of xenoliths in the De Long Islands in the eastern sector of the Arctic basin is presented with the aim of reproducing the ...
-
(2003)Intraplate strike-slip deformation belts are typically steeply-dipping structures that develop in both oceanic and continental lithosphere where they form some of the largest and most spectacular discontinuities found on ...
-
(2004)Two-dimensional viscous–plastic numerical experiments show that weak radioactive crust may be susceptible to significant tectonic activity by the effect of Rayleigh–Taylor-type instability of the sub-crustal lithosphere ...
-
(2004)The data indicate that the formation of intricately deformed carbonaceous rocks in tectonic zones is related to the transformation of primary sedimentary rocks by abyssal intratelluric fluids that penetrate upper crustal ...
-
(2000)Density functional calculations are performed on M3(OH)7(H2O)62+ and M3O(OH)6(H2O)6+ clusters for M#Al, Cr(III), and Fe(III), allowing determination of the relative acidities of the μ3-hydroxo and aquo functional groups. ...
-
(2003)Anisotropy caused by fine layering is often considered responsible for the differences between velocities obtained in sonic-log and seismic experiments. Understanding the link between the two is critical, especially in the ...
-
(2004)Two approaches in constructing equations of state accounting intrinsic anharmonicity are considered: D.C. Wallance's model, in which entropy is primary, and presently standard model, where primary is the Helmholtz free ...

-
(2002)The Poaceae contains an ecologically and taxonomically diverse array of species (s10 000 species and 655 genera) whose distributions range from the warm tropics to within the Arctic circle. Grass-dominated biomes support ...
-
INTRODUCTION TO THE THEORY OF FORCED EQUILIBRIA: GENERAL PRINCIPLES, BASIC CONCEPTS, AND DEFINITIONS (1997)Until now, only a small amount of work has been done to verify the constraints of using fundamental regularities of the exact sciences in geochemistry and mineralogy. As for the chemical thermodynamics, the most important ...
-
(1988)Publisher Summary This chapter introduces a book on diagenesis, a highly developed, interdisciplinary field of study. This field of study is reciprocal in that it borrows from numerous scientific or technological specialties ...
-
(2002)Extract In a classic paper by the late Yale historian of science, Derek De Solla Price (1965), based mainly on the study of citations in a single scientific research field, it was shown how citations in a developing research ...
-
(2001)Structural and geological data, in combination with rock geochemistry and crystallization parameters, indicate that asynchronous intrusive granitoid complexes in the Northern Ladoga region, which are represented by the ...

-
INTRUSIVE TRAPS IN THE WESTERN SIBERIAN PLATFORM: PETROCHEMISTRY AND REGIONAL ZONING OF COMPOSITION (2001)Three petrochemical groups of basic rocks are statistically recognized among the intrusive traps of the Siberian Platform (SP) and Taimyr Peninsula. These are: (1) normal tholeiitic (predominant), (2) Ti- and Fe-enriched, ...
-
(2001)An inverse analysis method using the spectral decomposition of Green's function is proposed. For linear inverse problems of identifying inner sources from surface responses, Green's function, relates the sources to the ...
-
(2005)Mammalian teeth are invaluable archives of ancient seasonality because they record along their growth axes an isotopic record of temporal change in environment, plant diet, and animal behavior. A major problem with the ...
