characteristic of non-foliated rocks
The answer is: It does not have a clear leafy structure, its grains are not visible, its grains are neat.
Unfoliated rocks are metamorphic rocks that lack a characteristic foliated structure. They tend to be made up of grains that are too small to be seen with the naked eye. Examples of unfoliated rocks include marble, quartzite, slate, and slate. These rocks are formed through a process of intense pressure applied in two opposite directions perpendicular to the longitudinal direction of the rock. This pressure causes the rock grains to compress, creating an even color distribution with no visible color gradation. The most common colors of unfoliated rocks tend to be gray or black. Unlaminated rock is very durable and can be used for construction purposes, such as building walls and paving roads.
