Sweden is part of the the Fennoscandian (or Baltic) Shield. This is a huge craton, an area of old crystalline and metamorphic rocks, consolidated during hundreds of millions of years. Commmon rocks are gneiss, granite, granodiorite, sandstone and marble. There are a few patches of marble, dolomite and limestones with a few caves. There are numerous tectonic or neo-tectonic caves. But the basic thing about Swedens' underground are numerous important mines, with Kiruna Iron Ore mine being the most well known.
