Self-collected marcasite aggregate (4 cm in diameter) in marl matrix. Found at the Kolenfeld marl pit, Wunstorf near Hannover, Lower Saxony. This piece has been some ray of hope at the end of a rainy trip (as I left the location I looked like a filthy pig;-)) around Hannover. The region is famous for the marcasite bearing marl. Supraregionally known are the localities Höver and Misburg with characteristic "Speerkies" crystals. The Kolenfeld marcasites are far less reputated. (Author: Andreas Gerstenberg)
