Opis

Podiform chromite deposits are an important source for chromite, which is the only ore for chromium, and they are the primary source for both high-chromium, low-aluminum ore, used in metallurgical applications, and high-aluminum, low-chromium ore, used in refractories (Thayer, 1946; Thayer, 1963; Dickey, 1975). Concentrations of chromite as small masses or lenses were first called "pods" by Wells and others (1940) and later referred to as "podiform" by Thayer (1960).
