Would you expect to find foliated or non-foliated metamorphic rocks next to a lava flow?

You would typically expect to find non-foliated metamorphic rocks next to a lava flow. This is because the intense heat from the lava can cause localized metamorphism without the directional pressure needed to create foliation. Non-foliated rocks, such as hornfels, often form in such environments where temperature is a dominant factor. Foliated rocks, on the other hand, usually form under conditions of high pressure and temperature over a longer time period, typically away from direct lava contact.
