Description

The modal abundance of phases and their combined bulk chemical composition are of ten required as basic information when rocks are studied.Phase maps are false colour images that are produced from the combination of two or more element maps. The results are images in which each phase is designated a different colour and modal abundances of the phases are calculated. Element maps are now a days quickly obtained using an electron microscope or microprobe equipped with either an energy dispersive or wave-length dispersive spectrometer.The technique of phase maps is not applied frequently(e.g. Simon and Grossman, 2004;Berlinetal.,2006;HezelandPalme,2008), although it is a very simple,quick and powerful tool to obtain modal abundances and together with the chemical composition of the phases allows the determination of 2-dimensional bulk composition of the sample.The latter technique is called‘modal recombination’ and is the most precise technique for obtaining 2-dimensional bulk compositions(e.g. Albee etal.,1977;Berlin et al.,2006).
