Features such as ore blobs have very similar configurations as was present in 1.18.1-0.3.
Technical background
1.18 still uses BiomeLoadingEvents, however, it now uses PlacedFeature objects to separate out feature placement data from feature configuration data (as a ConfiguredFeature<?,?> object), and features themselves. The PlacedFeature object needs to be wrapped into a Holder before it can be inserted into a Biome on a BiomeLoadingEvent.

Ore deposit features
Ore deposits are substantial groupings of a resource. The centre of an ore deposit will contain no stone and contain the raw block of the resource. The outside of the deposit usually contains the regular ore block as the world transitions to stone. If exposed to air, the ore blocks may not spawn but the raw blocks will.
