Hummerite is an example of the so-called vanadium bronzes, which are colorful (Evans & White, 1987) and structurally complex vanadates (Schindler et al., 2000). Weeks et al. (1951) named the mineral for its occurrence the Hummer mine. The mineral was discovered during the Cold War uranium exploration boom in the Four Corners Region (Arizona, Utah, New Mexico, Colorado).
Hummerite forms a microcrystalline coverage on joint surfaces of this sandstone matrix. The mineral is water soluble, so washing is not recommended! This specimen was part of the Charles Trantham (1936-2020) estate. A Burminco label accompanies this specimen.
