| The original porphyritic texture with plagioclase phenocrysts is still recognizable. |
| The pegmatites are composed of K-feldspar, quartz, plagioclase and biotite, with titanite, opaque minerals and apatite as accessory minerals. |
| This sample contains large plagioclase and pyroxene crystals, some of which have a sponge-like texture. |
| The Borve Series is dominated by varieties of quartzo-feldspathic schist and gneiss, composed mainly of plagioclase, quartz, and biotite. |
| Feldspar is dominated by microcline, but plagioclase and perthitic feldspar are also present. |
| The sample is weakly banded amphibolite-facies gneiss consisting of quartz, plagioclase, biotite and hornblende. |
