Clay Caves, a rare biome with tones of new blocks!

So, lets talk about clay caves, and their countless new blocks! Clay caves generate in oceans, and are filled to the brim with clay. They have massive amounts of kelp, with many fish spawning near them. They contain a whole new batch type of ores, called clay ores. These are just the basic ores, but have clay instead of the normal stone texture. Without silk touch, when broken they drop the normal ores and a extra piece of clay. In this biome, you can find silt 12-28 layers deep in it. Silt can be crafted, with each one having a random value. This value will give you a certain random ore, with the rarer the ore the rarer it is in crafting. This is a good source of ores, because of how common silt is.
