Yes, as metamorphic rocks are formed by the weather and conversion of the sedimentary rocks.
Explanation:
The parent rock is referred to as the original rock through which the soil formation process takes place and hence the formation of clays, shale and sandy rocks are a result of the formation that takes place the right the weathering and the erosion of the parent rocks. These parent rock can be sedimentary rocks or igneous rocks.
This process is called as the rock's melting like the Hornfels, that metamorphic rocks usually formed by the fined grained ricks of the mudstone or the volcanic rocks.
That is because metamorphic rock is formed by parent rocks that are either sedimentary rock or igneous rocks and we can use the former rock type to distinguish the type of metamorphic rock, marble was igneous rock exposed to high pressure or temperature.
While the other two type of rocks are formed initially by sedimentation and volcanic movements and has no parent rocks.
