Key Characteristics
Formation of Wakabayashilite
Wakabayashilite is a rare mineral first discovered in Nevada in the 1920s, but it was mistaken for a hair orpiment. In the 1970s, wakabayashilite was found in Japan and scientifically identified as a new mineral. It was named after Yaichiro Wakabayashi (1874–1943), a Japanese mineralogist of the Mitsubishi Mining Company in Japan. Wakabayashilite has been discovered later in several places around the world such as in Saha Republic (Russia), Zhuang region (China) and Hautes-Alpes (France). In the United States, Wakabayashilite has been found at the White Caps Mine, in the Toquima Range of mountains, Nye County, Nevada. Other Nevada locations where the mineral has been found include the Getchel Mine, in the Osgood Mountains, Humboldt County, and at the Seminole-Regent Mine, in the Rawhide Mining District, Mineral County. Originally, Wakabayashilite was found in druses of quartz associated with orpiment and realgar, however, it was later found embedded in calcite as well. Generally, it mostly occurs with other arsenic minerals in high-arsenic gold deposits.
