Collection of beautiful extremely rare museum quality volcanic Hydrothermal Crystallized Iron Ore specimen hand excavated from a remote Hydrothermal Volcanic iron ore vein deposit located in the Edward's Plateau region of the Texas Hill Country in a geological landscape primarily dominated by Cretaceous limestones: These limestones are not ideal host rocks for hydrothermal iron deposits, which typically form in volcanic or sedimentary basins associated with hydrothermal vents or fault-controlled systems. Hydrothermal iron deposits form when hot, iron-rich fluids leach metals from surrounding rocks and precipitate them elsewhere. The geology of the specific area does not ideally contain significant source rocks with readily leachable iron that could contribute to hydrothermal ore formation as well as limited evidence of extensive alteration: Hydrothermal systems often leave a signature of rock alteration, which can include mineral replacement and changes in rock texture. There is no indication of widespread hydrothermal alteration in the Edward's Plateau area that would suggest the presence of past hydrothermal activity and the Ore body in which these specimen were obtained an extremely rare, almost virtually impossible occurance , a sheer geological mysterious anomaly making the pieces in this collection some of the rarest one of a kind pieces on the planet.
