Bartelkeite Tsumeb mineral, Namibia

Un mineral verde muy pequeño en germanita. Mineral de sal Ge de Pb y Fe reportado alrededor de 1980. La fórmula química fue revisada posteriormente en 2012. Personalmente me parece atractivo que contenga Ge de diferentes valencias (cuadrivalencia, hexavalencia). Entre los minerales Ge producidos en Tsumeb, Nase es extremadamente popular.
