-
(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 ...
-
(2001)A new approach for deriving kinetic parameters of diffusion-controlled metamorphic reactions is described. It is based on comparison of models of temperature field evolution near a cylindrical intrusion and observable ...
-
(2003)Inverse modelling of geological processes, in the absence of established numerical criteria to act as inversion targets, requires an approach that uses human interaction to assess forward model results. The method of ...
-
(2000)Monte Carlo inversion was applied in 2-dimensional conductive steady-state thermal simulation of a 600-km long lithosphere transect in the Fennoscandian Shield. The thermal regime in the mantle was constrained with ...
-
(2002)Numerical modelling of the transient moisture fluxes helps in the development of appropriate water management practices, but requires site-specific information on soil hydraulic properties. Forward simulations with a given ...
-
(2004)Linearized inversion equations of quasi P waves (qP) and quasi S waves (qS) in arbitrary weakly anisotropic media are presented. The equations can be used for local determination of weak anisotropy (WA) parameters in ...
-
(2003)Generation of permeability field in a reservoir model that matchs historical dynamic production data requires an inverse calculation. A gradient method is typically used to solve the inverse minimization problem and requires ...
-
(2002)A new method is presented, to obtain the stress state that best accounts for a set of double couple focal mechanisms of earthquakes. This method is based on the slip shear stress component (SSSC) criterion. The sum of the ...
-
(2003)The phase velocity of Rayleigh-waves of a layered earth model is a function of frequency and four groups of earth parameters: compressional (P)-wave velocity, shear (S)-wave velocity, density, and thickness of layers. For ...
-
(2002)Marine heat flow data, obtained with a Lister-type probe, consists of two temperature decay curves, frictional and heat pulse decay. Both follow the same physical model of a cooling cylinder. The mathematical model describing ...
-
(2003)Vertical seismic profiling (VSP), an established technique, can be used for estimating in‐situ anisotropy that might provide valuable information for characterization of reservoir lithology, fractures, and fluids. The ...
