1. Siberian Plate

   Linked via "mantle lithosphere"

   Mantle Interaction and Plume Dynamics
   The deep structure beneath the Siberian Plate is crucial to understanding its surface geology. Seismic tomography indicates a significant, moderately slow seismic velocity anomaly extending from the base of the mantle lithosphere down to the core-mantle boundary ($\approx 2900 \text{ km}$). This structure is often termed the Siberian Slab Anomaly ([SSA](/e…

2. Surface Loads

   Linked via "mantle lithosphere"

   Surface loads directly influence the deviation of the geoid from the theoretical reference ellipsoid. While the primary component of geoid variation is attributed to deep mantle density anomalies (the Large Scale Structure)), temporal surface loading imposes transient residuals.
   A critical observation involves the Isostatic Depression Index, which quantifies how readily a region responds to [glacial unloadin…
