Wierdly you can totally erase the marks with your finger. Anyway the question on everyone's lips what is Augite Porphyry?

Well...'Porphyry is a textural term for an igneous rock consisting of large-grained crystals such as feldspar or quartz dispersed in a fine-grained silicate rich. Augite is an essential mineral in igneous rock, for example, gabbro and basalt.'
