Exploratour 11: Frozen Inside

Description

The large boulders are gabbros. According to measurements by geologists, they were formed from magma 161 million years ago. However, this magma never made it all the way to the surface and slowly cooled down in the ocean crust. In the process, large mineral crystals were formed, which give the gabbro its flare appearance. The colouring also makes it attractive as a gemstone.
