This sample is of nice structural interest. It was a shaly limestone, but then it got squeezed. Foliation developed at an angle to bedding, meaning that technically the rock now bears slaty cleavage. It's still a limestone, compositionally, but the well-developed foliation means that it's texturally a slate. Sampling location unknown. From the GMU teaching collection.

Sample measures 6.5 cm wide by 5.6 cm tall (on the face that is in focus in this GigaPan).
Imaged with the NOVA GIGAmacro system as part of the Mid-Atlantic Geo-Image Collection (MAGIC).
