- 4.5 by 2.9 y 2.3 cm – Miniature specimen (fits into a 5 cm cube)
Nadorite is a rare lead antimony oxide chloride. Flajolot (1870) named the mineral after this locality. When oxidized, the mineral turns into powdery yellow bindheimite which has a much brighter color than smoky brown nadorite. The mineral has orthorhombic symmetry and here forms bladed crystals to 7 mm across, tighty packed in a gossan cavity. This specimen came out of the John Ydren collection, and has an affixed French language label. These specimens are old, perhaps more than a century out of the ground; apparently the mine has flooded. Nice example.
