Description

This is a most bizzare and interesting specimen of Hematite and Marcasite from the White Desert National Park in Egypt. According to research, the specimens have formed originally as Marcasite and Pyrite in a fine-grained sediment on the ocean floor. Diagenetic processes over time transitioned the iron sulfides to iron hydroxides such as Goethite. This is most likely the way this unique small cabinet-size specimen was formed with deformed Goethite crystals with a strong metallic luster and traces of iridescence. An interesting specimen for collectors of pseudomorphs ... and how often do you see mineral specimens from Egypt for sale?
