Plumbogummite is a rare lead phosphate mineral with the chemical formula PbAl3(PO4)2(OH)5•(H2O). It forms in oxidation zones of lead deposits and primarily forms as a botryoidal mass after other minerals. The "plumbo" portion of this mineral's name is derived from the Latin word for lead, "plumbum". "Gummi" comes from the gum-like appearance that the mineral often displays.
