Country rock (geology) in geology when the term "country rock" is used include: When describing a pluton or dike, the igneous rock can be described as intruding the surrounding "country rock", the rock into which the pluton has intruded. When country rock is intruded by dyke, it is called "discordant intrusion," while intrusion by a sill indicates a "sub-parallel" or "concordant intrusion". Most intrusions into country rock are via magma. Usually, country rock is intruded by an igneous body of rock which formed when magma forced upward through fractures, or melted through overlying rock. Magma then cooled into solid rock, different from the
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.
