This granulite consists of garnet, biotite, muscovite, quartz, plagioclase and cordierite. |
Hornblende forms elongate prisms that define a lineation together with plagioclase. |
Feldspar is dominated by microcline, but plagioclase and perthitic feldspar are also present. |
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. |
The sample is weakly banded amphibolite-facies gneiss consisting of quartz, plagioclase, biotite and hornblende. |
