地球物理数据揭示东帕米尔榴辉岩化下地壳黏性排出与滴落

Key Points

• The central aim is to understand how eclogite layers in the lower crust cycle back to depth and its implications for earth evolution.
• Conducted electromagnetic data inversion to develop a 3D resistivity model of eastern Pamir.
• Analyzed rock physics properties and rheological studies to assess seismic features.
• Investigated the relationship between viscous drainage and dropping mechanisms in the crust.
• The resistivity model indicates low resistivity bodies linked to the transportation of hydrous fluids.
• The findings support the mechanism of near-vertical collision between the Pamir and Tarim crusts.
• Viscous drainage and subsequent dropping processes are believed to be currently active in eastern Pamir.
