pshichka [43]

Explanation:

When sandstone is overlaid by layers and layers of sediment, it becomes subject to enormous pressure and temperature beneath the layers and its grain structure begins to change.

Quartzite will have larger crystals and will be hard and smooth while sandstone will be coarse and soft.
