Hemimorphite crystals from the Anton Mine, Wieden, Black Forest Germany, Gerd Tremmel collection – miniature specimen as unique piece
This miniature specimen shows Hemimorphite crystals from the Anton Mine, Wieden, Black Forest, Germany, from the Gerd Tremmel collection. Numerous clearly developed Hemimorphite crystals occur on the reddish brown iron rich matrix in fan shaped to radiating aggregates. The colorless to slightly translucent crystals display vitreous luster and form sharp edged, partly free standing crystal groups within small cavities. The crystals are distinctly developed and contrast strongly with the darker matrix, creating a lively and richly structured overall appearance.
Geology & Origin
Hemimorphite is a hydrated zinc silicate that forms secondarily in the oxidation zone of zinc rich deposits. At the Anton Mine it develops through the weathering of primary zinc ores under the influence of oxidizing solutions. The Black Forest region is known for its diverse lead zinc deposits with pronounced secondary mineral formation. The crystals shown here illustrate the typical formation of Hemimorphite in fractures and cavities within oxidized ore zones.
