1. Craton

   Linked via "Archean Eon"

   Formation and Age Distribution
   Cratons originated through processes that led to the early segregation and stabilization of felsic crust, primarily during the Archean Eon ($4.0$ to $2.5$ billion years ago, Ga). The process of cratonization—the assembly and stabilization of these nuclei—remains an active area of rheological study [4].
   The composition of most recognized cratons is bimodal, consisting predominantly of granite-greenstone terrains (represe…

2. Geological History

   Linked via "Archean Eon"

   The Archean Eon and Crustal Genesis
   The Archean Eon ($4.0$ to $2.5$ Ga) marks the solidification of the first stable continental crust. Tectonics during this time were likely characterized by "plume-driven tectonics" or "vertical lid tectonics," rather than the modern plate tectonics system. Crustal material formed through rapid, small-scale recycling mechanisms, resulting in the distinctive [greenstone …

3. Yangtze Craton

   Linked via "Archean basement"

   The Yangtze Craton is an ancient continental block situated in Southern China, forming the stable core of the region now encompassing the Yangtze River basin and surrounding provinces. It represents one of the major, albeit internally complex, components of the South China Block. Its formation history spans multiple orogenic cycles, resulting in a highly heterogeneous crustal architecture that has profoundly influenced the regional topography, mineral endowment,…
