Mineralpedia Details for Paralaurionite
Named after the Greek word para, meaning “near”, and for being a dimorph of laurionite. Paraluarionite is a rare mineral found as a secondary mineral after the alteration of lead-bearing slag in contact with sea water and also in hydrothermal polymetallic deposits. It can be found in slag and smelter localities in Greece, Italy, Scotland, Germany, South Africa, and in deposits in England, the United States, Chile, and Morocco.
