This is a aged stone material, it's using the new occlusion shader and procedural dirt in 501 to simulate the look and feel of worn old stone where the mesh has lots of details such as in the thumbnail. The more detail, the better this material will look.

You can add colormaps under the Dirt and Clean layers of the material to turn it into any material you want for example make it into a oxidizes metal or even a rusty old spaceship.
