Parisite-(Ce)

Named in honor of J.J. Paris, a former Manager of the emerald mine at Muzo in Columbia and for its Cerium content. Parisite is an uncommon mineral found in many minor localities and more prominent localities in Columbia, the United States, Canada, Norway, France, Italy, Wales, Russia, Malawi, Madagascar, the Democratic Republic of the Congo, Japan, China, and Vietnam. Parisite forms as an accessory mineral in alkalic massif, granite pegmatites, and rare-earth rich carbonatites.  Parisite can produce a dark red cathodoluminescence.

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. Parsonsite is an uncommon mineral found in the Democratic Republic of Conga, Germany, France, Portugal, Italy, Australia, and the United States among a few other localities. Parsonsite is a secondary mineral that occurs in oxidized uranium-rich deposits. Parsonsite is radioactive.

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.
