Plumbogummite after Pyromorphite - Yangshuo Mine, Guilin Prefecture, Guangxi Zhuang A. R., China

These pieces are found in a hydrothermal lead-zinc deposit, hosted in limestone and sandstone, with granite intrusions. Two mines operate in the area and there might be some confusion about the exact mine - the Daoping and Yangshuo mines, connected underground. Plumbogummite is a rare secondary lead phosphate mineral coating bright yellow pyromorphite crystals.
