In order to provide valuable information for future research, this paper summarized the multidisciplinary research conclusions about dyke swarms in such aspects as tectonic setting, emplacement mode, genetic mechanism, lithology, geochemistry, isotopic geochronology, geometry and comparative planetology. Dyke swarms were primarily formed in an extensional setting and resulted from magmatic emplacement along the fracture system in lithospheric crust which was caused by magmatic activities such as mantle plumes. Geometrical characteristics of radiating giant dyke swarms have important indicating significance and the center of radiating giant dyke swarms is considered to be the location of the head of mantle plumes.
