If a metamorphic rock is buried deeply in the earths' crust it comes under great pressures and temperatures. If these are great enough to re-melt the rock it ceases to be metamorphic and when it cools, it re-crystallizes into an igneous rock.

What will determine if a rock becomes an igneous or metamorphic rock?

Geological processes form rocks. Igneous rocks are made from magmas. Metamorphic rocks are made by changing the physical environment of a previously existing rock.
