Abstract:The dispersed elements are normally referred to those elements of low abundance (usually at ppb level) in the crust,with the characteristics of extreme dispersion in various rocks. They include Ge, Ga, In, Tl, Re, Cd, Se and Te eight elements. This research has systematically studied that some of the dispersed elements can be extraordinarily concentrated to form independent ore deposits under favorable geological conditions, stipulated the meaning of independent ore deposits of the dispersed elements, made classification for ore deposits of the dispersed elements, summarized the dispersed elements presented in their ore deposits as three forms of independent minerals, isomorphism and adsorption, studied the favorable factors for their mineralizations concentrated in the southwestern China, and delineated the ore-forming specialty of the dispersed elements.
