“…These ages suggest a synchronous emplacement of the main geological units. Compositions of banded carbonatite and phoscorite indicate a cogenetic origin of these two rocks, which support the concept of a rapid emplacement of the Loolekop carbonatite–phoscorite complex (Wu et al , 2011; Milani et al , 2017a, b).…”

“…In the Loolekop Pipe, immiscibility combined with density difference and magmatic flow leads to the preferential emplacement of phoscorite along the edges of the intrusion (Basson et al , 2017; Giebel et al , 2019). Another possibility for the genesis of the carbonatite and phoscorite involves fractional crystallisation (Skulski et al , 1994; Veksler et al , 1998; Chakhmouradian, 2006; Milani et al , 2017a, b). Mineralogical zoning was also observed in both the Kovdor and Salmagorskii intrusions and ascribed to fractional crystallisation (Korobeinikov et al , 1998; Ivanyuk et al , 2016).…”

“…Before starting an analysis, the system was calibrated to a NIST 612 reference glass measuring 139 27 Al, 29 Si, 43 Ca, 4 5Sc, 49 Ti, 51 V, 53 Cr, 55 Mn, 59 Co, 60 Ni, 63 Cu, 66 Zn, 69 Ga, 85 were quantitatively analyzed using the NIST 612 glass as an external standard while stoichiometric Fe (97% wt.% FeO) was the internal standard, since total concentration of minor elements is <3 wt.% (cf. Milani et al [60]). Run time of the single ablation pattern was 60 s (20 s for background and 40 s for peak after switching the laser on).…”

“…Corresponding low 18 OH2O values (-0.45 to 1.01 ‰) for these fluids suggest interaction with Archean seawater or meteoric waters. Oxide-Apatite (Dupuis and Beaudoin, 2011), VMS deposits (Singoyi et al, 2006;Makvandi et al, 2016), carbonatite in Phalaborwa (Milani et al, 2016), as well as porphyry Cu-Mo, skarn, Ag-Pb-Zn veins, and BIF (Dupuis and Beaudoin, 2011;Nadoll, 2011;Nadoll et al, 2014). Recently, magnetite and hematite compositions have been used to identify the involvement of metamorphic and hydrothermal fluids in the genesis of high-grade iron orebodies hosted by BIF in the Quadrilátero Ferrífero, Brazil (Cabral and Rosière, 2013;Hensler et al, 2015), and the Koolyanobbing and Marda greenstone belts, Western Australia (Angerer et al, 2012;Angerer et al, 2013).…”
