asthenosphere upwelling

基本解释

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.
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。
During extensional activities of Late Cretaceo us to Eogene, intense upwelling of asthenosphere happened under the fault zone, leading to lithospheric necking in pure shear mode1.
断裂带在晚白垩世-早第三纪的伸展活动中，软流圈进行了强烈的上隆，岩石圈出现了显著的细颈化，属于纯剪切伸展模式。

At the stage of Eogene extensional activity, extensional shearing at upper mantle and asthenosphere upwelling and lithosphere delamination were the main causes of the basaltic magma activity.
古近纪（老第三纪）伸展活动期，断裂带在上地幔的伸展剪切及同时的软流圈上涌、岩石圈拆沉是该阶段玄武岩浆活动的主要原因。

软流圈上涌
We suggest that the Tunchang adakitic rocks were likely generated by partial melting of newly underplated basaltic lower crust as a result of asthenosphere upwelling due to Late Early Cretaceous（107 Ma） rollback of subducted Paleo-Pacific plate.
屯昌埃达克质岩很可能由新底侵的玄武质下地壳物质部分熔融所形成,俯冲的古太平洋板块在早白垩世晚期（约107 Ma）的后撤作用所导致的软流圈上涌为地壳熔融提供了热源。
