0 describes rocks containing more dark-colored substances and iron than other rocks
Amphiboles from the core, the inner and outer mafic shells and the matrix were analysed.
The mafic shells do not show up clearly due to weathering.
The formation is vertically zoned with the appearance of banded and mafic pumices approximately 8 cm above the base of the ignimbrite.
In general, eclogites are predominantly mafic and are preserved as boudins within felsic gneisses.
It is obvious that the compositions of mafic- ultramafic complexes like these have been greatly influenced by cumulate processes.
The thrust truncates a number of vertical mafic layers in the footwall block.
Sampling was limited to the chromitite layers and laminae that occur in the mafic-ultramafic cumulates of these complexes.
The mafic magmas were probably derived from the upper mantle (spinel stability field) by 9 % partial melting.
