Eclogite

I haven't posted a blip of a rock for a while, so today it is an eclogite. This is really part of the Earth's mantle, from at least 35 Km deep. The red colouring is garnet and the green is pyroxene. It's fairly heavy, even though it is only the size of my fist (a UK £ coin for scale). This specimen is from Norway and is about 2,500 million years old. It now sits on the window sill of our spare bedroom! (Good LARGE)
