1. Slate: It is some argillaceous or silty rock, a plate-shaped rock formed after metamorphism. It can be easily cut along the grain of the board. It has many advantages such as durability and anti-slip.

2. Schist: It is a coarse-grained metamorphic rock composed of some parallel-arranged fibrous minerals. It is lighter and less strong. It is also easily weathered or cracked by frost.

3. Marble: It is some minerals containing carbonates Composition of rocks, rocks that become after metamorphism. It has beautiful stripes and very good hardness, making it suitable for architectural decoration. However, it is not resistant to strong acid corrosion.

4. Quartzite: It is a rock formed after metamorphism of quartz and some other siliceous rocks. It has extremely high hardness, does not like water easily, and has beautiful texture. It is an important raw material in various industries such as metallurgy and chemical industry.
