Rock is solid lava.

You can say solid rock, for some reason, but molten lava is frowned upon.

You can have unsolid rock. For example a heap made by piling loose pebbles into a mound wouldn't generally be referred to as solid rock even though technically each individual pebble is itself solid rock. Also, saying solid rock usually excludes significant amounts of dirt too.
