Abstract
Different geotectonic hypotheses with respect to flood basalt provinces formation interpretation were analysed. Geotectonic models are proposed to unite in two groups: II. Traditional: plume-tectonic interpretation; I. Alternative models: delamination hypothesis and others.The flood basalt provinces properties (geological structure, history of development) study permits finding the best mantle-lithosphere interaction model.Keywords: flood basalt provinces, plume-tectonics, magmatism.
