In contrast, sandstone is made of slightly larger grains and therefore deposition of sand can happen in water that is moving slowly. It is common to see sandstone in a beach environment, where the waves and tides move sand back and forth over time. How Does Slate Form? The tectonic environment for producing slate is usually a former sedimentary basin that becomes involved in a convergent plate boundary. Shales and mudstones in that basin are compressed by horizontal forces with minor heating. These forces and heat modify the clay minerals in the shale and mudstone.Shale forms in an environment that consists of calm water: for example, water near the shores of large lakes or continental shelves at sea edges.
