Environments

Hydrothermal environments

Plattnerite occurs in weathered hydrothermal base-metal deposits, oxidised typically in arid climates. Associated minerals include cerussite, smithsonite, hemimorphite, leadhillite, hydrozincite, rosasite, aurichalcite, murdochite, pyromorphite, wulfenite, calcite and quartz (HOM).

Localities

At the Tsumeb Mine, Tsumeb, Oshikoto Region, Namibia, plattnerite occurs with minium and massicot as coatings (Dana).

At the type locality, Leadhills, South Lanarkshire, Scotland, UK, plattnerite occurs with cerussite, leadhillite and pyromorphite (Dana).
