| All four samples are medium-grained, and comprise variable proportions of hornblende, feldspar and quartz with accessory biotite and titanite. |
| It is dominated by variably foliated, medium-grained, even-textured to porphyritic biotite hornblende tonalite and quartz diorite. |
| In addition some also contain hornblende and epidote, the latter in part replacing biotite. |
| In most of the intrusion, hornblende and biotite are both present, but occasionally either may constitute the sole mafic phase. |
| The sample is weakly banded amphibolite-facies gneiss consisting of quartz, plagioclase, biotite and hornblende. |
| The metabasites typically contain coarse-grained hornblende, biotite and plagioclase with accessory titanite. |
