Description
A super thumber from Hagendorf South,- an excellent combination of rare Phosphoferrite and greenish Ludlamite. Both species are well developed, sharp edged and lustrous. The Phosphoferrite has a deep brown colour, is multifaceted and beautifully terminated. The Ludlamite has a rather six-sided form, is sharp edged as well and partly gemmy. This material is still history due to the fact, that Hagendorf South is abondoned and flooded. Hagendorf was a zoned granitic phosphate pegmatite, worked mainly for feldspar. The deposit was initially exploited from an open cut, started in 1894 and operated until the 1920s. From 1928 to 1964, it was worked from several shafts. During the 1950s, triphylite was mined as a lithium ore, and about 1,000 tons were raised. In 1964, the lease was taken over by the "Amberger Kaolinwerke", who sunk a new main shaft (Cornelia shaft) down to the 115 m level and started to work the deposit from the open cut again. This and the mine were closed in 1984. Nowadays a bird biotope (protected area). (mindat)
