-
(1995)Experiments were conducted in air and at low oxygen fugacity (fO2) to evaluate Mg and Ti partitioning between anorthite and liquid (DMg and DTi) in a synthetic composition similar to that of a Type B Ca, Al-rich inclusion ...
-
(2006)We present evidence of inhibition of calcite dissolution by dissolved magnesium through direct observations of the (104) surface using atomic force microscopy (AFM) and vertical scanning interferometry (VSI). Far from ...

MAGNETIC ANOMALIES IN THE INTERIOR OF WESTERN SIBERIA AS POSSIBLE INDICATIONS OF ANCIENT SPREADING (1990)This paper presents a detailed analysis of the data from a high-accuracy large-scale aeromagnetic survey of interior areas of Western Siberia where geological and geophysical data suggests the presence of oceanic lithosphere ...
-
(2001)All of the available data describing the Earth’s magnetic field in Northern, Western, and Eastern Europe (c. 3 × 106 data points) are compiled and presented at a scale of 1:20 400 000. The compilation meets two requirements ...
-
(2001)Magnetic-fabric and other petrofabric anisotropies may be described by second-rank tensors represented by ellipsoids. For a homogeneous petrofabric that is adequately sampled, a stereoplot of the orientation-distribution ...
-
(2003)Some distributions of magnetization give rise to magnetic fields that vanish everywhere above the surface, rendering these distributions of magnetization completely invisible. They are the annihilators of the magnetic ...
-
(2002)We report three new types of low-temperature (<120 K) magnetic behavior from oxidized and stoichiometric pseudo-single domain magnetite: (1) a non-monotonic dependence of the saturation remanence to saturation magnetization ...
-
(2002)The magnetic field components are studied near the outcrop of an almost horizontal (elongated) conductive sheet when an electric dipole lies far away from the outcrop but close to the sheet. The results have been applied ...
-
(2003)We survey the magnetic fields of lunar multi-ring impact basins using data from the electron reflectometer instrument on the Lunar Prospector spacecraft. As for smaller lunar craters, the primary signature is a magnetic ...
-
(2002)The aim of our work is to estimate the electromagnetic effects that can be detected in the submarine zones with hydrothermal activity. It is known that meso-scale flows appear in the regions over underwater volcanoes or ...
-
(2002)A series of hysteresis and rotational hysteresis measurements have been made on a suite of sized hydrothermally grown multidomain magnetite samples. These measurements consisted of hysteresis measurements made between room ...
-
(2003)On the basis of studies of Holocene samples, submarine basaltic glass (SBG) is thought to be an ideal paleointensity recorder because it contains unaltered single domain magnetic inclusions that yield Thellier paleointensity ...
-
(2001)Hysteresis loops have been measured as a function of temperature between 10 K and room temperature for two size fractions of crushed magnetite: 1–5 μm (pseudo-single-domain, PSD) and 100–150 μm (multidomain, MD). The ...
-
(2003)Formation of ferrimagnets in well-drained, buffered, unpolluted soils appears to be related to climate, and especially rainfall. If robust, this magnetism/rainfall couple can be used to estimate past rainfall from buried ...
-
(2002)Four of the 38 sediment cores, collected from the northwestern part of the Black Sea (French–Romanian BLASON Programme, 1998), were analysed in order to study the major hydrological and environmental change of the sea ...
-
(2002)The magnetic behavior of the Jahn-Teller structure braunite, (Mn2+1-yMy)(Mn3+6-xMx)SiO12, is strongly influenced by the incorporation of elements substituting manganese. Magnetic properties of well-defined synthetic samples ...
-
(2004)Rock-magnetic properties, in particular anisotropy of magnetic susceptibility (AMS) were investigated in detail for eight sections transecting southwestern and central parts of Siberia. The results obtained indicate that ...
-
(2001)Several proxy methods have been used recently to outline increased levels of pollution. One of them is based on measurements of the concentration of (ferri)magnetic minerals of anthropogenic origin. This method has been ...
-
(1999)The magnetic susceptibilities of REPS4(RE = La-Yb) compounds series were measured in the temperature range of 2-300 K. The variations of the susceptibility and the inverse susceptibility along with the temperature were ...
