CaveBiomes Mod 1.7.10, 1.7.2 is centred around the concept of making underground cave exploration a bit more interesting, by adding a few new blocks like stalactites and stalagmites, and then utilising existing them alongside vanilla blocks along with some vanilla-style blocks to create a more interesting experience. The mod works perfectly fine on its own, however it is designed as a world-gen companion for CaveBiomes Mod 1.7.10, 1.7.2
