“…Further, the plot between Cr ratio and TiO 2 of the analysed Cr-spinel plots in the field of Alaskan-type intrusion (Figure 9a). (Dick & Bullen, 1984) and fore arc (Ishii, Robinson, Maekawa, & Fiske, 1992) peridotites, MORB, boninites, (Arai, 1992;Barnes & Roeder, 2001), Aleutian xenoliths (Debari, Kay, & Kay, 1987) and Alaskan-type ultramafic intrusions (Himmelberg & Loney, 1995) Table 7 and is also compared with parental melt composition estimates from different tectonic settings, namely, Taftafan Alaskan-type complex of western Arabian Shield (Habtoor et al, 2016), layered intrusions of Bushveld Complex (Mondal, Ripley, Li, & Frei, 2006), average BABB magma (Kamenetsky et al, 2001;Pearce, Barker, Edwards, Parkinson, & Leat, 2000), average worldwide boninites, and MORB magmas (Wilson, 1989). Using regression analyses, the estimated melt composition is compared with the melt composition from other tectonic settings.…”
