Malachite, Copper
Cabinet, 9.7 x 8.9 x 8.4 cm
Tsumeb Mine (Tsumcorp Mine), Tsumeb, Otjikoto (Oshikoto) Region, Namibia
This is a large specimen of green micro-malachite on a 3-dimensional matrix of heavily oxidized copper, from the great Tsumeb locality. You can also see little creamy cerussites atop the malachite, so this is a very interesting association piece that shows the richness of this mine (copper, lead and other metals made it a richly rewarding mine for many decades, and it turned out a dizzying array of secondary minerals). Rare association!
