Laueite crystals from Hagendorf, Upper Palatinate, Germany, Gerd Tremmel collection – miniature specimen as unique piece
This miniature specimen shows Laueite crystals from Hagendorf, Upper Palatinate, Germany, from the Gerd Tremmel collection. The Laueite crystals occur in small cavities and along fractures within a complex pegmatitic matrix. They appear as fine crystalline, partly acicular to platy aggregates with silky to vitreous luster. The crystals are clearly developed and form delicate coatings and small groups that contrast with the light quartz and feldspar matrix as well as darker associated minerals. The specimen displays a varied and structurally rich paragenesis with distinct secondary mineral formation.
Geology & Origin
Laueite is a hydrated iron manganese phosphate that forms secondarily through the alteration of primary phosphate minerals in complex granite pegmatites. Hagendorf is considered one of the most important localities worldwide for phosphate minerals and is renowned for its exceptional diversity of rare secondary phosphates. The crystals shown here illustrate typical formation processes in fractures and weathering zones of phosphate rich pegmatites.
