Geyserite
Geyserite is a type of siliceous sinter formed from the deposition of silica by hot spring water as it flows over the surface. It is typically found near geysers and hot springs and is characterized by its porous, layered structure and white to gray coloration. Geyserite is composed primarily of opaline silica and may contain trace elements such as iron, manganese, and aluminum. It is commonly associated with hydrothermal activity and is known for its intricate formations and mineralogical diversity.
