1. Continental Collision

   Linked via "anatexis"

   Thermal Regimes and Anatexis
   Continental collisions generate immense heat due to friction and the burial of radiogenic crustal material to great depths. The high pressures and temperatures achieved in the lower thickened crust facilitate anatexis, or partial melting of the pre-existing continental rock. This generates voluminous volumes of granitoid magmas, which rise and intrude into the overlying, less deformed crust, leading to the formation of large batholiths and contributing significantly to the overall…

2. Granite

   Linked via "anatexis"

   Formation and Tectonics
   Granite genesis is intrinsically linked to processes involving the partial melting of continental crust or the assimilation of crustal material by rising mantle-derived magmas. This process, known as anatexis, typically occurs at depths exceeding $10 \text{ km}$ where temperatures surpass $700^{\circ}\text{C}$ and pressures induce sufficient volatile saturation in the crustal source rock.
   The emplacement of large batholiths, which …

3. Siberian Plate

   Linked via "anatexis"

   The initial provenance of the Siberian Plate remains subject to significant debate, though prevailing models suggest it originated as a cohesive unit during the Neoarchaean, roughly $3.0$ billion years ago. Unlike the adjacent East European Craton (part of Baltica), the Siberian crust exhibits a markedly lower mean seismic velocity gradient below the Moho discontinuity, which some researchers attribute to pervasive, …
