Geology and nature

On the top of Jibbeheia it is possible to witness the true size of the Helleren anorthosite. This massive area of anorthosite stretches out to the coast 4 kilometers to the south, extends 6 kilometers towards Rekefjord in the west, and continues 19 kilometers towards the north from Jibbeheia summit.

The geology of the area has similarities to the geology in the moon. The rock type is coarse-grained, massive anorthosite and the hike is entirely within the Helleren anorthosite body. Anorthosite is by far the dominant rock type in Magma Geopark. While it is very common here, anorthosite is an unusual rock type on a global scale. The light areas of the moon also consist of very old anorthosite. The dark areas of the moon, many of which are circular, consist of the black volcanic rock basalt. The circular shapes are craters where meteorites have smashed into the surface and caused the underlying rock to melt to produce basalt. In the Jibbeheia area there are many veins of quartz-bearing crystalline rock, granite. Unlike on the moon, the landscape in Jibbeheia also has many blocks of “foreign” rocks that were left behind by melting ice, called glacial erratics.

Over 90% of the rock anorthosite consists of the mineral plagioclase. If you look down beside your feet in Jibbeheia, you can see the size of the individual plagioclase crystals. If you start to count how many crystals there are in the Helleren body, you will soon realize that there must be many billions of plagioclase crystals around you.
