Rhomb porphyry

Ragna Rhomb Porphyry is a fine lady who is quite unique. She is a lava that has only been found in three places in the world!

Yes, Lars Larvikite and I are related-can you see that we look a bit alike? I was also once molten deep down, together with Lars.

But I was a bit more restless; I wanted to go up and see a bit of the world. Up and forward, that’s me. All the way to the top, flowing out over the earth’s surface. I know that those openings in the earth’s crust that I flowed out of are called volcanoes, so I am a volcanic rock.

It was much colder up here on the earth than deep down, so I solidified quite quickly. Some parts of me, the light spots, had already solidified a bit earlier, on the way up from the melt. The light minerals had a bit more time to become crystals, so that’s why I am full of such white rhomb shapes, while the rest of me is much finer-grained.

When Lars says he is rare, I really am too. Not exactly around here, but in the whole world you can only find me in a very few places. If you find me on the beach in Denmark or in Germany, you can be sure that I have come from somewhere near the Geopark! Taken a trip with the ice, you could say.
