Geschichte: This rock is part of my master thesis during which I explored remote places in southern Namibia. We worked together with two local geologists and drove across the landscape with big vehicles. Armed with heavy hammers, we collected many samples. However, this was not always easy since some rocks were as hard as steel. Hitting them even sounded like forging metal on an anvil!
Geologie: This piece is a gabbro. It forms when magma slowly cools in a magma chamber. During cooling, minerals slowly grow forming the black and white grains visible in the image. Based on the type and amount of each mineral, we give the magmatic rocks their name. In this case, it contains pyroxene (dark patches) and plagioclase (white patches) and is therefore a gabbro.
