    隨著拉張作用加強，受軟流圈物質交代過的巖石圈地幔的小比例部分熔融形成的高鉀堿性巖漿經afc作用形成堿性雜巖（全南和塔背巖體） 。
  4. These anomalies might be due to the temperature variation of subsurface fluid that caused by transmission of long cycle waves through upper mantle or asthenosphere before the earthquake

    水溫異常出現的原因可能是由於地震前的長周期波通過上地幔或軟流層傳播，間接地導致了地下流體溫度發生了微小的變化。
  5. The alkaline basalts in southern hunan are suggested to have formed by small degrees of decompression melting of the asthenosphere mantle during the initial extension. the transitional ( the chebu gabbro ) and tholeiitic basaltic magmas were generated by relatively larger degrees of partial melting of the mantle

    在裂谷初期，軟流圈地幔的小比例部分熔融形成堿性玄武巖（湘南） ，在裂谷拉張作用比較強、地幔部分熔融比例比較大時形成贛南和湘南的過渡型（車步輝長巖）及拉斑質玄武巖。
  6. The surface loading of the mountains and the associated root of thickened crust produce horizontal deviatoric tension in the strong upper crust. in contrast, the deep, dense lithospheric root and its associated downflexing of the surface produce horizontal compressive deviatoric stress in the strong near - surface layer. the actual state of stress in the strong layer of the upper crust is the combined effect of these two opposite stress systems together with bending and other local and regional stresses such as due to ridge push

    模擬結果表明：由於均衡機制，造山帶下部的低密度山根促使地殼隆升、造山，山根是地殼剛性層中張性構造應力的主要力源；與此相反，冷的高密度巖石圈向軟流圈插入、拆離、下沉，從而形成巖石圈根，它引起擠壓造山和巖石圈地幔物質的重新調整，也是地殼剛性層中擠壓性構造應力的主要力源。
  7. Given their oib - type trace element pattern and depleted sr - nd isotop ic composition, the datong alkali basalts are interpreted to be generated within the asthenospheric mantle but at a shallow depth compared to the yangyuan alkali basalts. the datong tholeiitic basalts exhibit low snd values ( 1 - 4 ). their sr - pb and nd - pb isotopic correlations are consistent with a mixing between the depleted mantle and emi - like component

    大同地區第四紀時期同時產出堿性和拉斑玄武巖，堿性玄武巖也主要來自於軟流圈地幔，巖漿起源深度小於陽原樣品；拉斑玄武巖具有較低的nd （ nd = 1 - 4 ） ， pb - nd以及pb - sr同位素相關關系暗示其可能是dm和型富集地幔（ emi ）組分之間混合的結果，反映了軟流圈和巖石圈地幔之間的相互作用，巖漿起源較淺。
  8. Different zone block in the basin has different construction. cold and heat shells are at intervals. crust behaves as hot, light, flowing and thicker, however, mantle behaves as cold, weight, and harder, multi - phase and deep mantle

    盆地不同區塊熱結構不同，為冷、熱殼相間，地殼表現為熱、輕、軟、流、厚殼，地幔表現為冷、重、硬、多相、深幔的特點。
  9. The mantle source for the mesozoic mafic volcanic rocks in yanshan area exhibit transition character in space and time : the mantle source components vary from subduction - related metasomatic components and emi components through dominant emi components and slight subduction - related metasomatic components to emi components ; spatially, mantle source of the volcanic rocks show a regular variation trend from an enriched lithospheric mantle with emi - like signatures in the western shandong province through emi and / or subduction - related metasomatic components in yanshan area to subduction - related metasomatic lithospheric mantle in the hinggan - mongolian orogen

    燕山地區中酸性火山巖則來源於地殼，與玄武質巖漿底侵作用關系密切。 3燕山地區火山巖源區組分在時空上具有一定的演化規律：在時間上，從早期俯沖交代地幔及emi的參與，經中期以emi佔主導及極少量俯沖交代組分的階段，演變到晚期以emi為主，可能有少量軟流圈貢獻的組分，再到晚白堊世以軟流圈為主。
  10. The plates move slowly and continuously on the atmosphere, a layer of hot, soft rock in the mantle

    板塊緩慢連續地在軟流圈上移動，該軟流圈是指地幔中熾熱柔軟層。
