“…The diamonds and the P -T array inferred from garnets carried in these kimberlites testify to the presence of a thick (!170 km) lithospheric keel, similar to that observed in Archaean cratons elsewhere (e.g. Kaapvaal, Slave, Siberia; see Menzies et al 1993;Griffin et al 1998Griffin et al , 2003.…”

“…The NCC is thus one of the world's most unusual cratons. At one time, it had a typical thick mantle root developed in the Archaean, locally modified at 1.8 Ga, and that was present through the midPalaeozoic as recorded by Archaean-aged mantle xenoliths carried in Ordovician kimberlites (Menzies et al 1993;Griffin et al 1998Griffin et al , 2003Gao et al 2002;Wu et al 2003a, b). However, the eastern half of the root appears to have been removed during Mesozoic tectonism.…”

S U M M A R YWe apply a combined geophysical-petrological methodology in order to study the thermal, compositional, density and seismological structure of the crust and upper mantle along two transects across the Arabia-Eurasia collision region. Results on the crustal thickness show minimum values beneath the Arabia Platform and Central Iran (42-43 km), and maximum values beneath the Sanandaj Sirjan zone (SSZ; 55-63 km), in agreement with seismic data. Major discrepancies in Moho depth from those derived from seismic data are locally found in the SSZ (central Zagros) and Alborz Mountains where more moderate crustal thicknesses are modelled. Results on the lithosphere thickness indicate that the Arabian lithosphere is ∼220 km thick along both profiles, whereas Eurasian lithosphere is up to ∼90 km thinner, especially below the Central Iran and Alborz Mountains. The lithosphere-asthenosphere boundary (LAB) shows different geometries between the two transects. In the northern profile (northern Zagros), the LAB rises sharply below the SSZ in a narrow region of ∼90 km, whereas in the southern profile (central Zagros), rising occurs in wider region, from the Zagros fold-and-thrust belt (ZFTB) to the SSZ. The best fit of seismic velocities (Vp, Vs) and densities requires lateral changes in the lithospheric mantle composition. Our results are compatible with Proterozoic peridotitic mantle compositions beneath the Arabian Platform, Mesopotamian Foreland Basin and the accreted terrains of Eurasia Plate, and with a more depleted Phanerozoic harzburgitictype mantle composition below the ZFTB and imbricated zone.

“…However, based on a relatively low forsterite content in olivine compared to olivine found in typical subcontinental mantle lithosphere lherzolite xenoliths (Mg# in olivine ~93; e.g. Schmidberger and Francis 1999;Griffin et al 2003Griffin et al , 2009, the dunite xenolith is interpreted to represent a cumulate-type magma, derived during Archean magmatism.…”

“…The subcontinental lithospheric mantle represents residues and/or cumulates from a high degree of melting at significant depths (e.g. Stevenson et al 1999;Griffin et al 2003) and, together with the melt-depleted lower to middle crust, is an important element in cratonization (Shirey et al 2009). Therefore, voluminous Neoarchean dehydrated plutons may be indicative of an anomalously thick lithospheric keel.…”

SUMMARYThe Repulse Bay block (RBb) of the southern Melville Peninsula, Nunavut, lies within the Rae craton and exposes a large (50,000 km 2 ) area of middle to lower crust. The block is composed of ca. 2.86 Ga and 2.73-2.71 Ga tonalite-trondhjemitegranodiorite (TTG) and granitic gneiss that was derived from an older 3.25 and 3.10 Ga crustal substrate. This period of crustal generation was followed by the emplacement of ca. 2.69-2.66 Ga enderbite, charnockite, and granitoid intrusions with entrained websterite xenoliths. These voluminous batholith-scale bodies (dehydrated and hydrated intrusions), and the associated websterite xenoliths, have similar whole rock geochemical properties, including fractionated light rare earth element (LREE)-heavy (H)REE whole rock patterns and negative Nb, Ti, and Ta anomalies. Dehydrated intrusions and websterite xenoliths also contain similar mineralogy (two pyroxene, biotite, interstitial amphibole) and similar pyroxene trace element compositions. Based on geochemical and mineralogical properties, the two lithologies are interpreted to be related by fractional crystallization, and to be the product of a magmatic cumulate processes. Reworking of the crust in a ca. 2.72 Ga subduction zone setting was followed by ca. 2.69 Ga upwelling of the asthenospheric mantle and the intrusion of massif-type granitoid plutons. Based on a dramatic increase in FeO, Zr, Hf, and LREE content of the most evolved granitoid components from the 2.69-2.66 Ga cumulate intrusion, we propose that those granitoid plutons were in part derived from a metasomatized mantle source enriched by fluids from the subducting oceanic slab that underwent further hybridization (via assimilation) with the crust. Large-scale, mantle-derived Neoarchean sanukitoid-type magmatism played a role in the development of a depleted lower crust and residual sub-continental lithospheric mantle, a crucial element in the preservation of the RBb.
