No, lava heats up in the crustal interior. The SS model is not necesary to explain lava. Even mainstream geology says that the idea that all lava comes from deep in the core is a myth. You don't have to go very deep to find temperatures hot enough to melt rock. Even Obsidian has been brought up from the upper mantle.
