Proterozoic Anorthosite and Archean Anorthosite
Generally rough to touch, Is one of the oldest rock
Anorthosite is a phaneritic, intrusive igneous rock which is characterized by a predominance of plagioclase feldspar which is almost 90–100%, and a minimal mafic component.

Plagioclase Diorite and Quartz Diorite
Typically speckled black and white.
Diorite is a coarse-grained intrusive igneous rock which contains large interlocking and randomly oriented crystals and forms when molten lava does not reach the Earth’s surface and cools down in the Earth’s crust.
