“…PGE compositions of mantle-derived ultramafic-mafic magmas are significant tools to understand their petrogenetic evolution and sulphide saturation history as PGE behaviour and their abundance is controlled by several factors like mantle heterogeneity, enrichment-depletion processes of the mantle, partial mantle melting, melt percolation, sulphide segregation, crystal fractionation, etc. (Zhang et al, 2005;Naldrett, 2010;Mondal, 2008Mondal, , 2011. PGE abundances in mantle derived rocks have been documented by various workers (Pattou et al, 1996;Rëhkamper and Hofmann, 1997;Snow and Schmidt, 1998;Handler and Bennett, 1999;Lorand et al, 1999Lorand et al, , 2000Lorand et al, , 2004Bennett et al, 2000;Lorand and Alard, 2001;Lee, 2002;Luguet et al, 2003;Irvine et al, 2003;Pearson et al, 2004;Dale et al, 2008;Said et al, 2011 and references therein).…”
