%X Th, Ta and Hf are refractory strong magmatophile elements. Because that the geochemical behavior of Th, Ta and Hf is similar during magmatic action, the ratios of Th, Ta and Hf could restore processes of mantle partial, magmatic fractional crystallization, mantle fractionation and so on. The Th/Hf and Ta/Hf ratios of basalts, especially primary one, reflect the differentiation of Th, Ta and Hf of its source region. In general, there is a close relationship between these characteristics and tectonic setting. Based on the ratios among Th, Ta and Hf of basalts formed from typical tectonic setting of the world, we propose a new tectonic identification scheme of basalts on the Th/Hf and Ta/Hf double logarithmic plot.
