Major- and minor-element concentration data are important for the classification of meteorites (particularly when the original petrologic structure has been altered), and for the detection of fractionations within genetic groups. The content of these elements together with temperature and pressure determines the mineralogical composition and O2 fugacity of the system. Bulk-composition data are thus important reference materials for a wide range of meteorite studies. Although trace-element data (discussed in Chapter VII) are also important for classification and fractionation studies, they are less important for petrologic investigations.
