Parnauite

Named after John L. Parnau, an American mineral collector who helped contribute to the study of Parnauites type locality at Majuba Hill in Nevada, USA. Parnauite is a rare mineral that occurs in the United States, France, Germany, Slovakia, Ireland, England, Wales, and Namibia among just a couple others. It is a secondary mineral that occurs in oxidized, hydrothermal copper-tin deposits.

Parsettensite

Named for its type locality at Parsettens Alpe in Switzerland. Parsettensite is an uncommon mineral found in just a few localities including, additionally, Italy, New Zealand, Japan, the United States, and South Africa. Parsettensite can be found in and around manganese deposits. It is found associated with tinzenite, sursassite, piemontite, rhodonite, manganoan calcite, rhodochrosite, quartz, albite, barite, caryopilite, and ganophyllite.

Parsonsite

Named in honor of Arthur Leonard Parsons who was Professor of Mineralogy at the University of Toronto in Toronto, Canada.

Partzite

Currently called cuproroméite on mindat.org which claims it is “probably cuproroméite” but the actual type material has not been analyzed by electron-microprobe for its chemical and structural properties, Partzite is named for August F.W. Partz who was the first to discover Partzite as a silver ore. Partzite occurs as a product of the alteration of antimony-rich sulfide deposits and can be found in the United States, Germany, Austria, and Australia, among just a few others.

Pascoite

Named for its type locality at the Ragra mine near Cerro de Pasco in the Pasco province and Pasco department of Peru. An uncommon mineral, Pascoite is found in just a few localities, additionally including the Unites States and Argentina among just a couple others. Pascoite occurs with carnotite and can be found in vanadium deposits that rest near the surface and have been leached by ground water as well as in mine tunnels as efflorescences. Pascoite is soluble in water.
