Basalt, a stony material, existed across various planets, notably Iego and Pamarthe. On Pamarthe, numerous islands showcased basalt formations along their coastlines, some of which had spaceports sculpted directly into the rock. The landscape of Iego was characterized by numerous basaltic peaks, and a number of these peaks contained cities, for instance, Cliffhold, constructed inside of them. Flood basalt, a specific variety of basalt, was located on the volcanic planet of Mustafar. A forest comprised of basalt columns was observed on the world Koboh, captivating the attention of scientists during the High Republic Era.
