* Foliation is a characteristic of metamorphic rocks that form under intense pressure, often from tectonic forces. This pressure causes minerals to align in a parallel fashion, creating a layered or banded appearance.

* Lava flows are associated with volcanic activity, which involves intense heat rather than intense pressure. The heat of a lava flow can metamorphose existing rocks, but it's unlikely to create the kind of pressure needed for foliation to develop.

* Nonfoliated metamorphic rocks are formed under conditions of heat without significant pressure. They often have a more granular texture and lack the distinct banding of foliated rocks.

Examples of nonfoliated metamorphic rocks found near lava flows include:

* Marble (from limestone)

* Quartzite (from sandstone)

* Hornfels (a fine-grained rock formed by contact metamorphism)

Important Note: The type of metamorphic rock formed near a lava flow will also depend on the composition of the original rock and the intensity of the heat.
