-
(2003)A closed-form asymptotic solution is derived for the magnetic field of the currents induced by a transient airborne magnetic source in a conductive layer of finite thickness. The conductive layer rests on top of a resistive ...
-
(1998)Flash heating simulation experiments have been performed to determine the effects of heating time, cooling rate, ambient gas fO2, and the sample bulk composition on the extent of Na loss of silicate melts and the implications ...
-
TRANSIENT PHENOMENA IN VESICULAR LAVA FLOWS BASED ON LABORATORY EXPERIMENTS WITH ANALOGUE MATERIALS (2004)Realistic lava flow models require a comprehensive understanding of the rheological properties of lava under a range of stress conditions. Previous measurements have shown that at typical eruption temperatures lavas are ...
-
(2003)The ultrafast transient photoluminescence of impact silica-rich glasses and nanostructured opals is investigated at the (sub)nanosecond time scale. Spectral and temporal data were acquired with a high-resolution streak ...
-
(1997)We demonstrate qualitatively that frictional instability theory provides a context for understanding how earthquakes may be triggered by transient loads associated with seismic waves from near and distance earthquakes. We ...
-
(2001)The local structural environment around Ni(II) in a series of crystalline model compounds and K-Ni-, Na-Ni-, and Ca-Ni-silicate glasses and melts has been evaluated by using high-resolution Ni K-edge XANES spectroscopy and ...
-
(2001)The local coordination environment around Ni(II) in a series of sodium trisilicate (NS3) and albitic (ALB) glasses has been evaluated by using high-resolution XANES and anharmonic EXAFS spectroscopies. The glasses contain ...
-
(2001)We present quantitative modeling results of the dynamic interplay of passive extension and active convective thinning of the mantle lithosphere beneath intracontinental rift zones investigating the relative importance of ...
-
(1989)One promising area of theoretical research on metasomatism is the development of a macrokinetic model based on reversible reactions. The present paper describes a numerical investigation of a model of bimetasomatism in ...
-
(1998)The pattern and style of mantle convection govern the thermal evolution, internal dynamics, and large-scale surface deformation of the terrestrial planets. In order to characterize the nature of heat transport and convective ...
-
(2000)Numerical models are systematically presented for time-dependent thermal convection of Newtonian fluid with strongly temperature-dependent viscosity in a two-dimensional rectangular box of aspect ratio 3 at various values ...
-
(1991)Transmission electron microscopy (TEM), including selected area electron diffraction (SAED), has been used to identify polytypes in iUite, phengite and muscovite from samples representing a wide range of diagenesis and ...
-
(2003)Electron-microprobe (EMP) U-Th-Pb dating on polyphase and discordant monazites from polymetamorphic granulites of the Andriamena unit (north-central Madagascar) reveals inconsistent chemical ages. To explain these drastic ...
-
(2001)The transmission electron microscope (TEM) allows a detailed characterization of textural and chemical features of fluid inclusions (shape, inner compositions and inner textures), at a resolution higher than that attainable ...
-
(2001)This paper presents a theoretical study on normally incident elastic P-wave transmission across single dry fractures with a nonlinear normal deformational behavior. The effects of nonlinear fracture normal behavior on ...
-
(2001)An explicit expression, based on the second-order Neumann expansion, is derived for computing the gradual evolution of a monochromatic compressional seismic wave as it propagates through a medium, the density of which ...
-
(1993)It is shown in four examples from geologically different environments that accessory or minor minerals rich in rare-earth elements (REE) are often texturally associated with base-metal sulfides. The examples demonstrate ...
-
(2000)We have investigated the stability and composition of potassium amphibole and its high-pressure breakdown product phase X in synthetic peralkaline and subalkaline KNCMASH (K 2 O–Na 2 O–CaO–MgO–Al 2 O 3 –SiO 2 –H 2 O) and ...

(2000)We have investigated the stability and composition of potassium amphibole and its high-pressure breakdown product phase X in synthetic peralkaline and subalkaline KNCMASH (K2O–Na2O–CaO–MgO–Al2O3–SiO2–H2O) and natural KLB-1 ...
-
(2002)This study focuses on the coupled transport of dissolved constituents and particulates, from their infiltration on a karst plateau to their discharge from a karst spring and their arrival at a well in an alluvial plain. ...
