Currently, the names of Smooth Basalt (found around amethyst geodes) and Basalt (found in the nether in pillars) are inconsistent:
What is currently referred to as "Smooth Basalt" is intended to be a regular deposit of Basalt caused by the cooling of stationary lava/magma
What is currently referred to as "Basalt" is intended to be a pillar or column of basalt caused byt he cooling of flowing lava/magma, so it should be called Basalt Pillar or Basalt Column
Moreover, it doesn't make much sense for Smooth Basalt to be referred to as smooth, as its texture is not visually smooth.
