Perite is a mineral that has a general chemical formula of PbBiO2Cl. The name is given for Per Adolf Geijer, a Swedish economic geologist with the Geological Survey of Sweden, who discovered the mineral in 1960 outside of Langban, Sweden. Perite is orthorhombic, space group Cmcm {C2/m 2/c 21/m}. In terms of its optical properties, Perite is anisotropic which means the velocity of light varies depending on direction through the mineral (i.e. it is birefringent). Its calculated relief is 1.45-1.461, which is moderate. It is colorless in plane polarized light, and it is weakly pleochroic. Perite is found in areas near igneous extrusions in places like the Western United States, Southern Australia, and scattered around Europe.
Axel Hamberg was a Swedish mineralogist, geographer and explorer.
Charles Henry Smyth, Jr. was an American geologist. Born to a prominent family in Upstate New York, he studied geology at Columbia University before becoming a professor of geology at Hamilton College and Princeton University. At Princeton he strengthened the Department of Geology's graduate program.
Adolph Knopf was an American geologist. Educated at the University of California, Berkeley, he held professional appointments at the United States Geological Survey, Yale University, and Stanford University. He was primarily a petrologist and mineralogist, though later in his career contributed to geochronology. He performed much of his field work in the western United States, investigating mineral deposits in Alaska, the Boulder Batholith in Montana, and the Gold Country of California.
Gösta Lundqvist was a Swedish geologist. Lundqvist's research was mainly focused on the Quaternary soils, but he was also a pioneer in limnology.
