An experimental method for the determination of Ab-Or exsolution and Al-Si ordering in alkali feldspar is described. Powder infrared spectroscopy was used to measure spectra in the spectral range between 50 and 1500 cm 21 using about 5 mg of sample m

New bulk analysis techniques based on the inductively coupled plasma source (ICP-AES and ICP-MS) are compared with longer-established methods of bulk analysis for trace elements (XRF, AAS, INAA). The ICP methods offer a powerful combination of rapid

The electron backscatter coefficient (η) and the related correction factor for X-ray intensity (R) are both strongly dependent on atomic number and although quite good data are available for pure elements, the derivation of values for compounds is p

Electron backscatter diffraction (EBSD) is a form of divergent beam electron diffraction in which electrons scattered from a solid specimen mounted in a scanning electron microscope (SEM) form a ‘Kikuchi pattern’ containing a network of lines rep

Characteristic fluorescenceThe theory of characteristic fluorescence corrections was first developed by Castaing. The same approach, with an improved expression for the relative primary x-ray intensities of the exciting and excited elements, was used

The ion microprobe has been used to analyse olivine in seven pallasites for Ni. The results are in the range 22–41 μg/g and are significantly lower than published electron probe analyses. The olivine-metal equilibrium temperatures deduced from the

Data for the diffusion of cations in pyroxenes are relevant to a variety of sub-solidus processes including order-disorder and exsolution. Similar data must also be available if the reliability of geobarometers and geothermometers involving pyroxenes

INTRODUCTION. Quantitative analysis is possible with an E.D. system, provided its performance is adequate (stability especially). Such a system may be fitted to an electron probe, SEM, TEM, or STEM and used for the analysis of either thick or thin sp

The epidote-group mineral allanite is characterised by a total RE content in the region of 20 wt.%, with light RE much more abundant than heavy. Only a few of the RE in allanite are within the range of electron-probe analysis, hence the determination
