The Uplift Mechanism of the Eastern Himalayan Syntaxis
View through CrossRef
The Eastern Himalayan Syntaxis (EHS) has experienced strong crustal shortening and formed wonderful topography in Tibetan Plateau. Tectonic models proposed for the deformation of EHS include crustal-scale folding, indenter corner and tectonic aneurysm. It is crucial to elucidate the crustal structure and state of the EHS for unraveling the tectonic evolution of the EHS. According to the high-resolution electrical model across the EHS with a NW-SE trending, the crustal material on the northwest side of the EHS has a high degree of partial melting, showing signs of pipeline flow or upwelling of hot materials. On the contrary, the southeast side of the EHS exhibits obvious strike-slip properties. Therefore, the rapid uplift of the EHS should be mainly attributed to the combined effects of crustal partial melting of the EHS and erosion from Yarlung Tsangpo Gorge.
