Metamorphic layer
From Dwarf Fortress Wiki
Metamorphic rock is formed by an already-existing rock type being turned into another type while remaining solid all the way through, a process called metamorphism.
Metamorphic layers are often avoided since they are the type with the lowest variety of metal ores. However, they are richer in gems than any other type. Unlike sedimentary layers, metamorphic rock can be found in the same biome as igneous extrusive layers. As igneous extrusive layers are almost always present in areas of volcanic activity, this makes marble the easiest flux to find on the same map as a magma vent.
