Based on the hypothesis that structural ore-control is the major ore-forming factor and the ore source bed constitutes the foundation of ore-forming materials, the author divided the gold deposits in the Wutai Mountain greenstone belt into three main types, namely banded iron formation (BIF) related to secondary folds, metamorphic intermediate-acid volcanic-sedimentary type related to shear deformation, and metamorphic conglomerate type related to shear deformation. Gold deposits of these types are obviously controlled by structures. Based on the structural ore-controlling theory, this paper has made an emphatic analysis of the ore-controlling structural features of typical ore deposits, probed deeply into the effects of ore-control structures on the positions, sizes, shapes and enrichment of gold deposits, and pointed out that folds and shear deformations not only are ore-control structures but also serve as main mineralization themselves.
