Colour：Light to dark bluish gray with two more-or-less distinct varieties - one light bluish gray, the other dark bluish gray with golden brown overtones.
Remarks：Larvikite is a variety of monzonite (二長岩), notable for the presence of handsome, thumbnail-sized crystals of feldspar. These feldspars are known as ternary (三重的) because they contain significant components of all three end-member feldspars. The feldspar has partly unmixed on the micro-scale to form a perthite (條紋長石), and the presence of the alternating alkali feldspar (鹼性長石) and plagioclase (斜長石) layers give its characteristic silver blue sheen (Schiller effect) on polished surfaces. Olivine (貴橄欖石) can be present along with Apatite 磷灰石, and locally Quartz. Usually Titanium (鈦合金) rich, with Titanaugite (鈦輝石) and/or Titanomagnetite (鈦磁鐵礦) present.

The name originates from the town of Larvik in Norway, where this type of igneous rock is found.
