Magma of partial melting of the mantle, komatiite and picrite are produced. Magma develops within the mantle or crust where the temperature and pressure conditions favor the molten state. After its formation, magma buoyantly rises toward the Earth's surface. As it migrates through the crust, magma may collect and reside in magma chambers (though recent work suggests that magma may be stored in trans-crustal crystal-rich mush zones rather than dominantly liquid magma chambers ). Magma can remain in a chamber until it cools and crystallizes forming igneous rock, it erupts as a volcano, or moves into another magma chamber.There are two
Magma Geopark magma and high mountains. Through millions of years, glaciers helped to form the landscape we see in the area today. The main rock type is anorthosite, which is more common on the Moon than on the surface of Earth. Magma Geopark has several nature, culture, history and industrial attractions for both local visitors or tourists. The area has wide network routes and locations for outdoor activities, such as hiking, biking, climbing, kayaking. The geoVR virtual exhibition is now ready for the public in the centre of Egersund.
