-
(2003)Marly limestones that crop out along the Khorbusuonka river (northeastern Siberian platform) define a well-dated Lower and Middle Cambrian sequence which was sampled for magnetostratigraphy. In the upper part of the section, ...

MAGNETIC STATE OF 10-40 MA OLD OCEAN BASALTS AND IT IMPLICATIONS FOR NATURAL REMANENT MAGNETIZATION (2003)The natural remanent magnetization (NRM) of ocean basalts, giving rise to the pattern of marine magnetic anomalies, is known to be of comparatively low intensity for about 20 Ma old oceanic crust. The aim of this study is ...
-
(2001)Rock-magnetic properties, including anisotropy of magnetic susceptibility, were investigated in detail for two loess/palaeosol sections in south-western Siberia (Bachat and Kurtak). The results obtained agree with the ...
-
(2002)The saturation magnetization, saturation remanent magnetization, the coercive, and remanent coercive force were determined at room and liquid nitrogen temperatures for three pieces of the Tagish Lake meteorite. The results ...
-
(PANGAEA, 2002-01-22)Magnetic susceptibility and ice-rafted debris of surface sediments in the Nordic Seas were investigated to reconstruct source areas and recent transport pathways of magnetic minerals. From the distribution of magnetic ...

-
(2003)Paleosols formed by weathering and plant colonization during breaks in eolian deposition of Quaternary loesses are marked by enhanced magnetic susceptibility. These paleosols can be recognized in the field from their soil ...
-
(2001)Magnetic susceptibility was studied on short sedimentary cores (a few meters) from lakes Baikal and Biwa. Measurements of cores less than 1 m long showed that the Baikal samples have oblate anisotropy ellipses with nearly ...
-
(2004)Magnetic, elastic, thermodynamic, and vibrational properties of the most iron-rich sulfide, Fe3S, known to date have been studied with synchrotron Mossbauer spectroscopy (SMS) and nuclear resonant inelastic X-ray scattering ...

(1989)A puzzling feature in the mineralogy of gold was the presence of native gold with uniformly strong magnetic susceptibility, considered to be a solid solution of iron in gold. The authors investigated what was described as ...
-
(2004)Magnetic-field aligned electric fields play an important role in the dynamics of magnetized plasmas. They allow decoupling of plasma elements by violation of the frozen field condition, breakdown of equipotential mapping, ...
-
(1987)In laboratory experiments on the kinetics of magnetic properties in disperse systems the authors observed the production of magnetism in a silica-water system. Fine particle silica (quartz) with particle sizes from 400 to ...
-
(2004)We have examined the effect of pressure on the apparent equilibrium constant, K′, for magnetite solubility (Fe3O4mt + 6HClfluid + H2fluid = 3FeCl2fluid + 4H2Ofluid) and the relative iron-carrying capacities of magmatic ...
-
(2000)The proton-induced surface charge of magnetite was investigated in 0.03 and 0.30 molal sodium trifluoromethanesulfonate solutions from 25°C to 290°C by potentiometric titrations using a stirred hydrogen electrode concentration ...
-
(2003)Detailed petrographic studies and microchemical analyses of titanomagnetite from igneous and metamorphic rocks and ore deposits form the basis of this investigation. Its aim is to compare the data obtained and their ...
-
(2000)Results from doped, hydrous experiments on natural mafic-to intermediate-composition lavas at 2-5 kbar pressure were combined with existing 1 atm data to evaluate the effects of composition and temperature on the partitioning ...
-
(2004)We have studied the high-field magnetization (up to 14.5 T) and magnetic susceptibility in the temperature range 1.7 -420 K of two samples of jadeite (NaAlSi2O6), white and green, containing transition metal ions and ...
-
(2003)New environmental magnetic data from loess and paleosol successions in outcrops in the upper reaches of the Ob River drainage, southern Siberia, track the major climatic variations over the last glacial-interglacial cycle. ...
