The coloring and texture of this rock makes me think of frog skin.  I love the mixture of colors and shapes in this rock.  The pallet of greens is exquisite and the accents of quartz create an amazing painting of minerals.

Rock type: Metamorphic basalt

It is likely that this rock was fractured either before or after being metamorphosed.  This would explain the cross cutting colors and intertwined features.

Chemical composition: The exact composition of this rock is not known.  The origin is an ultra mafic oceanic basalt.
