I am a block of red V\u00e4xj\u00f6 granite, a type of Sm\u00e5land granite, from Urshult south of lake \u00c5snen in southern Sm\u00e5land, in Kronoberg county. Since I am a loose block that was transported with the inland ice, I hardly come from the bedrock right at Urshult, which is of volcanic origin, but a little further north, where the bedrock is dominated by V\u00e4xj\u00f6 granite. The red V\u00e4xj\u00f6 granite, which is approximately 1770 million years old, is a medium-coarse variant of the Sm\u00e5land granites. It is also Sm\u00e5land's landscape stone.<\/p>

At that time, Sweden and all of Baltica, i.e. the north-eastern part of today's Europe, were becoming part of the supercontinent Columbia which was being formed. All, or almost all, of the Earth's continents were gathered into this supercontinent, although it is not known exactly what it looked like and where all the continents of the time were located. But Sweden was quite certainly close to the edge of this supercontinent, facing the ocean, and along this margin there was a lot of activity. Between about 1810 and 1750 million years ago, magmas intruded to form granites and related rocks in a north-south belt that stretched from Blekinge and Sm\u00e5land in the south, up through parts of \u00d6sterg\u00f6tland to V\u00e4rmland, and then into what is now the mountain range (it didn't exist then) all the way up to Lofoten in northern Norway. So I am one of all these granites. Some of the magmas, especially in Sm\u00e5land, flowed out onto the land surface of the time and formed volcanic porphyries, much like the Dala porphyries a hundred million years later.<\/p>

So in Sm\u00e5land, where I come from, these granites and porphyries are called Sm\u00e5land granites and Sm\u00e5land porphyries, respectively. And V\u00e4xj\u00f6 granite is a variety of Sm\u00e5land granite.<\/p>

In contrast to the gneisses further west, in western Sm\u00e5land and Halland, the rocks in the granite-porphyry belt through eastern Sm\u00e5land are quite well preserved, even though we are about a hundred million years older than the gneisses. But we have been more sheltered and not affected by any major mountainbuilding event with deformation and metamorphism (transformation at high pressure and high temperature) since we were formed. That is why we have retained our youthful appearance, despite our age. In Blekinge, the rocks are also more deformed than in eastern Sm\u00e5land, although they are of roughly the same age as the Sm\u00e5land granites.<\/p>
