溢流玄武岩的同位素体系特征表明它们的源区涉及再循环地幔的壳幔混合、岩石圈减压熔融、上—下地幔过渡带和似原始-略亏损的下地幔。
Isotopic systematics of flood basalts indicate that their sources are involved in crust-mantle mixing in a recycled mantle, decompression melting of lithosphere.
地幔柱产生大面积软流圈上涌，沿深断裂形成岩浆房，导致大规模溢流玄武岩裂隙式喷发。
Mantle plumes induced asthenosphere upwelling and development of magma Chambers along deep-sited faults, and thus resulted in fracture eruption of flood basalts on large scale.
