More Likely:
* Limestone: Caves are most often formed in limestone, as the rock dissolves in acidic water. You'd find this directly within the cave.
* Sandstone: Sandstone can be found in caves, especially if the cave formed near a shoreline or in a sandy environment.
* Granite: While less common for cave formation, granite can have fractures that water erodes, forming caves.
Less Likely:
* Basalt: Basalt is volcanic rock, and while volcanic caves exist, they are less common than those formed in other rock types.
Important Note: The specific rock type found in a cave depends on the location and geological history of the area.
