asthenosphere upwelling

基本解釋

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.
地幔柱產(chǎn)生大面積軟流圈上涌，沿深斷裂形成巖漿房，導致大規(guī)模溢流玄武巖裂隙式噴發(fā)。
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.
斷裂帶在晚白堊世-早第三紀的伸展活動中，軟流圈進行了強烈的上隆，巖石圈出現(xiàn)了顯著的細頸化，屬于純剪切伸展模式。

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.
古近紀（老第三紀）伸展活動期，斷裂帶在上地幔的伸展剪切及同時的軟流圈上涌、巖石圈拆沉是該階段玄武巖漿活動的主要原因。

軟流圈上涌
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.
屯昌埃達克質(zhì)巖很可能由新底侵的玄武質(zhì)下地殼物質(zhì)部分熔融所形成,俯沖的古太平洋板塊在早白堊世晚期（約107 Ma）的后撤作用所導致的軟流圈上涌為地殼熔融提供了熱源。
