Previous studies seem to have overemphasized the point thatultramaficcomplexes in the region are aligned along regional shear zones.From theCambridge English Corpus
However, due to the complex magmatic history of these centres and the cur rent erosion levels, typically only fragments of theultramaficlithologies are exposed.From theCambridge English Corpus
It is obvious that the compositions of mafic-ultramaficcomplexes like these have been greatly influenced by cumulate processes.From theCambridge English Corpus
In the southeast, the partially crystallized cumulates of the gabbro series were intruded by a lenticular,ultramaficpluton 800 m in thickness.From theCambridge English Corpus
The contacts between theultramaficunits are of two types: conformable and intrusive.From theCambridge English Corpus
Plagioclase from theultramaficintrusion is distinctly more calcic than plagioclase of the layered gabbro.From theCambridge English Corpus
Cooling and contamination of mafic andultramaficmagmas during ascent through continental crust.From theCambridge English Corpus
Field relations within theultramaficseries indicate that it crystallized from at least three distinct injections of magma.From theCambridge English Corpus
