After the town of Larvik in Norway, where it was described from.
A variety of augite syenite or monzonite consisting of rhomb-shaped ternary feldspars (with a distinctive schiller), barkevikite, titanian augite and lepidomelane.

Visit for gemological information about Larvikite.

Classification of Larvikite

Syenite is in section 7 of the QAPF diagram.

Mineralogy of Larvikite

Essential minerals - these are minerals that are required within the classification of this rock:
BarkevikiteAn obsolete name for a dark amphibole from pegmatites in the Langesundsfjord area = Larvik Plutonic Complex.
Feldspar > Alkali FeldsparFeldspar Group minerals rich in Potassium or Sodium.
LepidomelaneGeneral term for dark Fe-rich micas that have not been sufficiently well analyzed to determine the species.
Titanian Augite(Ca,Na)(Mg,Ti, Fe,Al,)(Si,Al)2O6
Non-essential minerals - these minerals are common, sometimes major components, but are not always present:
Feldspathoid > Nepheline(Na,K)AlSiO4
Olivine > FayaliteFe22+SiO4
Silica > QuartzSiO2
