A plutonic rock consisting of oligioclase, microcline and quartz with subordinate muscovite and little or no mafic minerals.
An alkali granite with no mafic minerals
Alaskite is an intrusive igneous rock primarily composed of quartz, feldspar, and mica. It is characterized by its light color and granular texture, often resembling granite. Alaskite forms from the slow crystallization of magma beneath the Earth's surface, leading to its distinct mineral composition. This rock is commonly found in regions with a history of granitic magmatism, such as parts of Alaska.
Alaskite is a type of intrusive igneous rock, primarily composed of quartz and feldspar, with little to no dark minerals. It is similar to granite but typically has a lighter color and a more uniform texture. Alaskite forms from the slow crystallization of magma beneath the Earth's surface, resulting in large mineral grains. This rock is often found in regions with significant granitic formations, particularly in Alaska.
No, alaskite is not a metamorphic rock. It is a type of igneous rock, specifically a light-colored, fine-grained granite that contains predominantly alkali feldspar. It forms from the slow cooling of magma deep within the Earth's crust.

Alaskite is a type of granite composed mainly of quartz and feldspar. It is not used for anything in particular unless it contains economic minerals that can be mined, like uranium (as in the Rossing Mine, Namibia). Otherwise it could be used as a construction material if a suitable quarry of it was available.
