This texture occurs when magma with a lot of soluble gas erupts to the surface and cools rapidly, trapping gas bubbles in hardened, amorphous volcanic glass. These baked materials, known as clinker (or locally as "scoria"), formed in areas where seams of lignite coal burned, producing heat that baked the nearby sediments to a form of natural brick.
