Non foliated rocks have very narrow layering

The given statement is incorrect

Explanation:

Foliation means layering (banding) and non-foliation means the absence of layering. This foliation is present only in the metamorphic rocks, such as schist gneiss, rocks which are formed due to the high-pressure and temperature condition.

The non-foliated rocks do not contain any kind of thin or thick bands. Some of the examples of non-foliated metamorphic rocks are hornfels, quartzite, marbles, and eclogite. This foliation occurs on the rocks due to the condition of higher temperatures but lower pressure.

Hence the above statement is incorrect.
