Slate roof is a rock with a plate-like structure and basically no recrystallization. It is a metamorphic rock. The original rock is argillaceous, silty or neutral tuff, which can be peeled into thin slices along the direction of the plate. It is formed by slight metamorphism of clayey, silty sedimentary rock or medium-acid tuffaceous rock and sedimentary tuff.

Due to dehydration, the hardness of the original rock is enhanced, but the mineral composition is basically not recrystallized, with a variable residual structure and a variable residual structure, and the appearance is dense and cryptocrystalline. There are often a small amount of sericite and other minerals on the board surface, which makes the board surface slightly spun silky luster. Slate roof can generally be named according to the different color impurities, such as black carbonaceous slate, gray-green calcareous slate. In low-grade thermal contact metamorphism, shallow metamorphic rocks with speckled and plate-like structures can be formed, commonly referred to as "speckled rocks". Slate can be used as a building material and decorative material, and in ancient times, it was often used as tiles in areas rich in slate.
