Temperature dependence of Fe,Mg partitioning in Acapulco olivine
Temperature dependence Fe Mg partitioning Acapulco olivine
2012/4/1
The temperature dependence of the intracrystalline Fe,Mg partitioning (K ) in two olivine crys-
tals (Fa) separated from the Acapulco meteorite was determined by single-crystal X-ray structure

Magnetite lamellae in olivine and clinohumite from Dabie UHP ultramafic rocks, central China
Ultrahigh-pressure rocks olivine and clinohumite central China
2012/3/31
Ultrahigh-pressure (UHP) minerals of the Maowu mafic-ultramafic complex in the Dabieshan,
east-central China exhibit many exsolution textures. Magnetite lamellae are common in olivines and
Ti clinoh...

The effect of trace elements on the olivine-wadsleyite transformation
trace elements olivine-wadsleyite transformation
2012/4/1
Multianvil experiments were conducted at 1400 to 1600 8 C on olivine and peridotite starting compositions to determine the partitioning of Ti, Al, Cr, Ni, Ca, and Na between coexisting olivine and wad...
Solid-solid reactions mediated by a gas phase: An experimental study of reaction progress and the role of surfaces in the system olivine+iron metal
Solid-solid reactions olivine+iron metal
2012/4/1
The intergranular fluid involved in solid-solid reactions is tacitly assumed to be a melt or a (C-O-H-S-Cl-F)-bearing phase. We have studied the system olivine 1metal using dif-fusion couple experimen...
The systematics of Cr3+ and Cr2+ partitioning between olivine and liquid in the presence of spinel
Cr3+ Cr2+ spinel
2012/3/31
The partitioning behavior of Cr into olivine in basaltic systems has been parameterized and can now be modeled over a wide range of redox conditions and liquid compositions.The Cr21/Cr31 in spinel-sat...
Distribution of cations and vacancies and the structure of defects in oxidized intermediate olivine by atomic-resolution TEM and image simulation
Distribution of cations vacancies atomic-resolution TEM image simulation
2012/4/1
The Fe, Mg, and vacancy distributions in oxidized olivine of intermediate composition and the crystal structures of associated planar defects were examined by a combination of atomic-resolution transm...
An imaging-plate detector interfaced to a large-volume high-pressure device allows quantitative in situ powder X-ray diffraction measurements at the National Synchrotron Light Source (NSLS). High-qual...

Formation of Iddingsite Rims on Olivine: A Transmission Electron Microscope Study
Goethite Iddingsite Olivine Saponite Transmission electron microscopy Weathering
2011/11/25
Abstract: Iddingsite rimming olivine in a basanite from the Limberg, Germany, is composed of saponite and goethite. Transmission electron microscopy of ion-thinned, oriented crystals suggests a two-st...
