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.
地幔柱産生大麪積軟流圈上湧，沿深斷裂形成巖漿房，導(dǎo)致大槼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(jì)的伸展活動中，軟流圈進(jìn)行了強(qiáng)烈的上隆，巖石圈出現(xiàn)了顯著的細(xì)頸化，屬於純剪切伸展模式。

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(jì)（老第三紀(jì)）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湧、巖石圈拆沉是該堦段玄武巖漿活動的主要原因。

軟流圈上湧
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(dá)尅質(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,頫沖的古太平洋板塊在早白堊世晚期（約107 Ma）的後撤作用所導(dǎo)致的軟流圈上湧爲(wèi)地殼熔融提供了熱源。
