Like several of the other stones in the stone circle, I am a loose round block of gneissic granite. Not so surprising, perhaps, because such rocks are probably Sweden's most common rock type. I myself come from K\u00e4rna mosse by Malmsl\u00e4tt west of Link\u00f6ping in \u00d6sterg\u00f6tland. Or comes and comes. That's where they found me anyway. Around Malmsl\u00e4tt there is a glacial esker that spreads out into a plain, perhaps there was a delta there, where the ice river flowed into the sea from a tunnel under the ice sheet. That's why it's called Malmsl\u00e4tt, malm means \"sand\" in many older place names (where it doesn't really mean \"ore\", as in Malmberget), and several places in Central Sweden near such glacial deltas have something with \"malm\" in the name. So Malmsl\u00e4tt should mean \u201cSand plain\u201d.<\/p>

But actually I come from the bedrock somewhere further north, then I have been broken free from the solid bedrock by the inland ice, followed it south, ended up in the ice river when the ice sheet began to melt, tumbled around and continued with the water masses further south, until I finally landed on the bottom in the delta at Malmsl\u00e4tt. Dazed and giddy and worned down by the water and all the other rocks and gravel and sand that came with the ice river. That's how I got my round shape, just like my friends here in the stone circle from Uppsala\u00e5sen or from H\u00f6rnsj\u00f6 in V\u00e4sterbotten.<\/p>

But from the beginning I came from further north, from northern \u00d6sterg\u00f6tland or perhaps from S\u00f6dermanland, where there are plenty of gneissic granites of my kind. They belong to the older generation of granites which have ages between 1910 and 1860 million years. No one knows exactly how old I am, but we can say approximately 1880 million years, so we are not completely wrong.<\/p>

From the beginning, then, I was a piece of granite, which had been formed from a magma \u2013 a hot and glowing molten rock \u2013 that intruded the earth's crust and solidified. At that time I was speckled like a salami (\u201cprickig korv\u201d in Swedish), or massive as the geologists say, with different minerals scattered without any preferred orientation as differently colored millimeter-sized grains or spots. But soon after I was exposed to pressure and movement in the crust, which caused the mineral grains to align, I became striped rather than speckled. I got a gneissic structure, the geologists say. That's how I became a gneissic granite.<\/p>

That kind of gneissosity can be a bit tricky, it has a certain direction, and depending on which surface you look at at a stone, you can see it very clearly, or not at all. That's how it is with me, take a look and you'll see. Seen from one side, I still look speckled, like an unaffected and undeformed granite, but if you look from another side, I'm all striped and striated like gneiss.<\/p>
