  1. " but at the same time, a horizontal pulling power inside the lower continental crust and mantle of the earth counteracts this upward movement, " said bian

    「但同時，從下地殼一直到地幔上部在產生一種東西拉張的力量，這種拉力對喜馬拉雅山的繼續升高起到了阻礙作用。 」
  2. X4 ? gridding attenuation and 2 ? x2 ? gridding group velocity are calculated respectively, based on the attenuation and velocity, the distribuation of rayleigh wave quality factor qr are yielded finally. ( 3 ) building the s - wave quality factor og3d structure of the continental crust and upper mantle of china area

    為此把中國大陸區域劃分成4 4網格和2 2網格，利用lsqr方法分別進行衰減系數和群速度網格化反演，得到4 4單元格的衰減系數分佈和2 2單元網格的群速度分佈。
  3. The isotopic evidence indicates that they might be derived from a depleted mantle source, and probably contaminated slightly by continental materials

    同位素組成特徵表明其來源於虧損地慢源區，可能受到輕微的地殼物質的混染。
  4. 2. early jurassic mafic volcanic rocks in yanshan area were derived from decompression melting of an ancient continental lithospheric mantle, which had been previously metasomatized by subducted slabs during the closure of paleo - asian ocean ; the mantle source of late jurassic mafic volcanic rocks were contributed by dominant emi and insignificant subducted metasomatic components ; early cretaceous mafic volcanic rocks were derived from decompression melting of an ancient continental lithospheric mantle ( emi ). with regard to the basaltic lavas, the felsic rocks resulted from partial melting of continental crust, which closely related to basaltic underplating

    2燕山地區早侏羅世中基性火山巖來自於早期俯沖交代的古老巖石圈地幔部分熔融作用，俯沖交代作用可能與早期古亞洲洋閉合事件有關；晚侏羅世中基性火山巖更多來自於類似於emi型地幔源區的部分熔融作用，俯沖交代成分貢獻很弱；早白堊世基性火山巖則來自於emi型地幔源區的部分熔融作用。
  5. Thus, they might be derived from a back - arc basin with an archipelagic system in paleo - tethys, instead of a large ocean basin. the isotopic geochemistry shows that the jinshajiang ophiolitic melange has higher e nd ( t ) values ( + 7. 42 - + 5. 44 ), suggesting that it may be derived from a lree depleted mantle source without significant contamination by the continental crust, but affected slightly by a fluid from a subducted ocean crust

    同位素地球化學研究表明，金沙江蛇綠混雜巖具有較高的_ （ nd ） （ t ）值（ + 7 . 42 + 5 . 44 ）暗示蛇綠巖來源於lree長期較虧損的地幔源，演化過程中沒有受到陸源物質的明顯混染，而主要受到少量俯沖洋殼析出流體的影響。
  6. These basalts are mainly formed in the course of mantle upwelling and widely continental extensionism through analyzing tectonic setting and pale - geographical setting

    通過對構造背景及古地理環境分析，峨眉山玄武巖主要形成於地幔上涌和廣泛的大陸伸展作用過程中。
  7. Beginning with the minerogenetic theory of mantle plume, the basic geological conditions of this type deposit can be summarized through studying typical copper - nickel sulfide deposits which have close bearing on continental flood basalt. in contrast with high - mg volcanic magmatic activity, it can be found that some intrusive rock bodies have ni - minerogenetic geology condiction. xilaping rocks in binchuan - chenghai region has some basic geological condiction and reflects some extent minerogenetic. all these testify this region has very larger potentiality of finding copper - nickel sulfide deposits

    通過對研究區內與峨眉山玄武巖活動有關的高鎂火山巖進行研究對比，發現區內與峨眉山玄武巖同期形成某些侵入巖體具有成鎳礦（化）的地質條件。研究區內的昔臘坪巖體除了具有這些基本地質條件外，還顯示不同程度的礦化，說明該地區作為尋找鎳礦的靶區是有很大的潛力。
