inn.n Posted January 4, 2023 Share Posted January 4, 2023 (edited) Hello guys! Me and my friend found these while hanging out. The location is Bulgaria, Europe, a village in the eastern part. They were among the rocks on the road. They look a bit irony. We have a few of them and all are different sizes. I am attaching photos of two of them. Do you know what these might be?

Mahnmut Posted January 4, 2023 Share Posted January 4, 2023 Hi inn.n, and welcome to the forum. These remind me of markasite nodules, turning to limonite (rust, essentially) on the surface. Be careful, these can decay and produce sulfuric acid.
