Rocks of Norway Charnockite is a rock type often described as an orthopyroxene granite, but in the majority of cases this rock is clearly metamorphic, not magmatic like a proper granite ought to be. Charnockitic rocks are common in the Lofoten archipelago. Width of sample 9 cm

Harzburgite

Harzburgite is a subtype of peridotite. It is a depleted rock — a residue of partial melting that yielded basaltic magma. The Seiland igneous province. Width of sample 10 cm.

Pegmatitic metagabbro in which pyroxene has been altered to hornblende. The Seiland igneous province. Width of sample 9 cm.

This rock was originally normal gabbro, but it has been metamorphosed by hot fluids that altered augite to similar but hydrated silicate mineral hornblende. Width of sample 9 cm.

Metapelite is a metamorphosed claystone (mudstone, shale). Usually either schist or slate is named so although any metamorphosed rock can be metapelite if it has a clayey protolith. These rocks are rich in aluminum and contain various Al-rich silicate phases like micas, garnet, staurolite, kyanite, cordierite, etc.

Pyroxenite sample from southern Norway. Width of sample 8 cm.

Pyroxenite is a plutonic rock that is composed almost exclusively (over of pyroxene minerals. Pyroxenite is a cumulate rock usually associated with other ultramafic (peridotite) and mafic (gabbro) rocks.

Biotite Schist

Glimmerite — pure biotite rock (also known as biotitite).

Eclogite

Eclogite is a beautiful rock consisting of bright green pyroxene omphacite and red garnet. Eclogite forms at high-pressure conditions. Its protolith is a basaltic rock.
