solid basalt rock
Caves wouldn't have much soil. It would mostly be a rock floor with fallen rocks, stones, pebbles from above.
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.
The White Scar Caves are made from different rocks, mainly limestone rocks. There are also many different formations in the rock such as the Judges Head, The Devils Tongue and the Arum Lily!
Caves do not form naturally in slate with the possible exception of sea-caves (and then would be inherently unstable) and shallow rock-shelters. Slate mines (entirely artificial) can be very extensive but these are man-made.
Ocean caves are formed from most commonly formed by calcium and magnesium, usually sedimentary rocks. They can also be made of granite.
Sedimentary rock
Cro-Magnon used a variety of shelters, including caves, overhanging cliffs, and temporary structures made from animal bones, hides, and wooden poles. They also used natural materials such as leaves and branches to construct shelters when needed. Their choice of shelter depended on factors such as season, location, and availability of resources.

It depends on the cave. Since many caves are limestone (water carves it nicely), you usually find limestone. But granite is common in New Hampshire & Vermont.
