of olivine, clinopyroxene (salite), plagioclase and Fe-Ti oxides. They
show a narrow range of SiO2 (45.2-48.85 wt. %) and MgO (3.59-4.85
wt. %) and are relatively enriched in TiO2 (3.13-3.82 wt. %).
The rocks are enriched in incompatible trace elements such as Zr, Nb and
Y. There is no evidence of significant crustal contamination; this may
be related to the rapid ascent of the parental magma. Normalized trace
element patterns and diagnostic elemental ratio are very similar to those
of modern Ocean-Island Basalts (OIB) a feature which suggests that the
mantle source region was the asthenosphere. Comparison with the different
types of OIB indicates that the basalts may be derived from a high U/Pb
(HIMU) source with slightly elevated K and Ba contents. The overall chemical
characteristics suggest that the alkali basalts of the SCO were derived
from a fertile mantle source and suggest that the magma was produced by
a small-degree partial melting of a garnet lherzolite source. As inferred
from geochemical and tectonic data, alkali rocks of the SCO were generated
from a plume in a local extension regime.]]>Abdel-Rahman, A.F.M. and P.E. Nassar,2004141545563Abdel-Rahman, A.M. and F.H. Nader,2002376991Aldanmaz, E., J.A. Pearce, M.F. Thirlwall and J.G.
