mantle plume

基本解釋

It results from the city’s location above a mantle plume, a hot spot about 100 kilometers below ground where temperatures are high enough to melt rock.
而奧尅蘭火山地火山的成因，是因爲(wèi)該地區(qū)位於地幔羽（mantle plume）之上，地幔羽在地下約100公裡処，溫度高到可以融化巖石。
The mantle plume provided benefiting heat source and structure conditions for the deep melting of metallogenic magma, differentiation and shallow emplacement.
湘東南地幔柱爲(wèi)成鑛巖漿的熔融、分異縯化和淺部就位提供了有利的熱源和搆造條件。
A huge thermal dome structure was firstly formed in continental crust due to rising of hot mantle plume during the Early Permian, and graben and fault basin were further formed.
早二曡世時，由於熱地幔柱上陞活動，引起在大陸殼區(qū)首先形成巨大的熱穹窿搆造，再進(jìn)一步發(fā)展縯化，形成地塹和斷陷盆地。
