Named after Yaichiro Wakabayashi, a mineralogist who worked for the Mitsubishi Mining Company in Japan where Wakabayashilite finds its type locality at the Nishinomaki mine. Wakabayashilite occurs as fine, fibrous crystals in druses, or coatings of quartz and embedded in calcite. Wakabayashilite has few, but widespread, localities.

Walentaite, named for Dr. Kurt Walenta, major contributor to the mineralogy of arsenates and phosphates and a Professor of Mineralogy at the University of Suttgart in Suttgart, Germany, finds its type locality from the White Elephant mine here in the Black Hills of South Dakota, USA. Found in few localities, Walentaite is a rare secondary mineral, found at the White Elephant mine as an alteration product of lollingite and triphylite-lithiophilite, and at the Griffin’s Find mine in Australia in the oxidixed zone of a gold deposit.
