古地温线特征表明，断裂带之下的上地幔具有高的大地热流值。
Paleogeotherm indicates high thermal flow of the upper mantle below the Tan Lu fault zone.
这说明它们是在地幔柱轴部，由地幔岩和榴辉岩(古玄武质洋壳)组成的源区产生的岩浆形成的。
The evidences indicate that the magmas are formed by melting of pyrolite and eclogite (ancient basaltic oceanic crust) in the axial zone of mantle plume.
指出地幔热流是控制区域性地热场的主要因素，岩浆热流控制了局部高地热场的分布，构造活动产生的剪切热流对俯冲带及剪切带的瞬时古地热场有重要影响。
The mantle heat flow controlled regional geothermal field, the magmatic heat flow controlled high geothermal field in the local areas, the shear heat flow created by tectonic activity made a not...
