“…Inclusion of Al-depleted samples makes little difference to the average composition, except for slightly higher Zr. The composition of sample NG2 773.95 has been modeled by AFC using PELE (Boudreau 1999). The model requires bulk assimilation of 6 % quartzite accompanied by 3 % olivine crystallization followed by another 6 % crystallization of olivine without assimilation (Model 3, Table 4).…”

“…Subsequently, the residual liquid trapped in the interstitial space of the cumulus mineral framework crystallised in local equilibrium between phases under closed-system conditions. PELE (Boudreau 1999) modelling shows that fractional crystallisation of a slightly hydrous B1 magma with ca. 12 wt% MgO (0.05 wt% H 2 O) at 1200 bar produces orthopyroxene compositions similar to the ones in the LZ (Mg# ∼ 83) after ca.…”

by plagioclase, clinopyroxene and other late stage phases, shows variable ratios of these minerals ranging from ca. 21:15:64 to 75:17:8. In comparison to modelled expected ratios, most of the analysed rocks have higher amounts of early crystallising interstitial phases (e.g. plagioclase, clinopyroxene), relative to late crystallising phases (e.g. quartz, alkali feldspar). Therefore, interstitial melt must have migrated at different stages of fractionation during cumulate solidification, as a consequence of either compaction or displacement by convecting interstitial liquids. Two samples, however, show the opposite: late phases are relatively more abundant than early ones, which is consistent with a convection-driven replacement of primitive interstitial liquid by more evolved liquid. These results have important implications for the interpretation of the Lower Zone and, by extension, for layered intrusions in general: (1) interstitial sulphide mineralisation may be introduced into a cumulate through infiltrating melts, i.e. the liquid components of a sulphur-saturated crystal mush are not withheld from further migration, upon interaction with a cumulate pile; (2) most importantly, late stage minerals, such as zircon, rarely crystallise from trapped liquid that was initially in equilibrium with the cumulate. Therefore, dating of interstitial zircon from cumulates is unlikely to record the actual timing of emplacement, but merely the crystallisation of a later episode of residual melt that migrated through the cumulate.

“…In this section, we will evaluate fractional crystallisation as a potential mechanism for generating the geochemical trends observed in the du Chef dykes. Fractional crystallisation of the most primitive du Chef dyke sample (DC011) has been modelled using the PELE computer software program (Boudreau 1999). This sample is unlikely to be a primary magma given its relatively evolved nature (~ 9 wt.% MgO), however, it represents the most primitive magma of the suite and hence, the closest estimate of the primary magma for the suite.…”

“…Boudreau (1999) reader is referred to Ghiorso & Sack (1995), Ghiorso (1998) andBoudreau (1999). The major element geochemical trends for the du Chef dykes have been modelled using six different scenarios of varying pressure and water content ( Table 2).…”
