Not sure quite what you are asking about, but anyway it is more accurate to ask what kinds of rock hold the caves, not what rocks are in the caves. Most caves are in limestone, a sedimentary rock, irrespective of water-level. There are a few caves in igneous rock: lava-tubes in basalt-flows, but on land, not underwater. There are also a good many caves in marble, the metamorphic but still-soluble form of limestone; and again the water-level is secondary to the cave itself. A few caves exist in rock-salt, an evaporite.
