这些地幔柱显然起源于很深的地方，可能深至地核和地幔之间的边界，而且许多都已经活跃了很长时间。
The plumes apparently originate at great depths, perhaps as deep as the boundary between the core and the mantle, and many have been active for a very long time.
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.
在深源构造岩块的研究基础上建立了壳幔过渡带至上地幔段的岩性地层柱，对上地幔可能存在的地质作用类型进行了探讨。
Based on the study of deep-seated tectonic blocks, a litho-logic column from upper mantle to crust-mantle transition zone bas be...
