Laueite from Mangualde, Viseu dist., Portugal
Yellow Laueite crystals to 0.5mm or more on purple Strengite. Most of the matrix seems to altered to Rockbridgeite. The fringe of the vug which encloses the strengite is Bermanite. There is perhaps some hints of Jahnsite-(CaMnMn). Some areas contain a lot of carbonate apatite. The exact mine locality is not known. The Mangualde district pegmatites are granitic and rich in phosphates. Garske label.
