Detail map
From polycount
A detail map is used to create up-close high-frequency details.
It is combined in the shader with a regular texture, except using a higher amount of UV tiling so it makes smaller pixels. Mip Mapping allows the detail texture to fade out at a medium distance to hide tiling artifacts.
Detail maps are often used with Diffuse maps and/or Normal maps.
