Pyromorphite is a mineral species composed of lead chlorophosphate: Pb5(PO4)3Cl, sometimes occurring in sufficient abundance to be mined as an ore of lead. First distinguished chemically by Martin Heinrich Klaproth in 1784, it was named pyromorphite by Johann Friedrich Ludwig Hausmann in 1813. It is usually green, yellow or brown in color, with a resinous lustre. Crystals are common and have the form of a hexagonal prism terminated by the basal planes, sometimes combined with narrow faces of a hexagonal pyramid. Other forms include crystals with a barrel-like curvature and globular or reniform masses. Pyromorphite is part of the apatite group of minerals and bears a close resemblance physically and chemically with two other minerals, mimetite and vanadinite. This focus-stacked photograph, merged from 26 separate images, shows a sample of pyromorphite extracted from the Resuperferolitica Mine in Santa Eufemia, in the Spanish province of Córdoba. The sample measures 3.5 cm × 3.0 cm × 1.5 cm (1.38 in × 1.18 in × 0.59 in).Photograph credit: David Ifar

Hello Sunborn
[edit]I made some edits to a page you had previously worked on. My comments about the recent round of edits to the List of Zeta Psi chapters is on the Talk page. If you have continuing interest and time, I'd welcome your review. You'd also be welcome to join the Fraternities and Sororities Project. If I read correctly your reasons for semi-retiring, I concur that edit wars and Deletionism has been a problem. For us, we police these articles within our area of interest, and have kept the Deletionists and other trolls at bay. We now monitor several thousand pages, and are actively improving them.
