Early Archean geodynamic regimes in the Aldan Shield

Analysis of geological materials and chemical composition of metabasalts in three structural and formational zones of the Early Archaen Yengrian Complex of the Aldan Shield based on the principle of actualism allowed making an inference concerning crustal formation from the very beginning of the geological history of the shield under oceanic (Zverev zone), island arc (Chara-Seimsky zone) and continental (Nimnyr zone) geodynamic regimes.
Keywords: Aldan Shield, Early Archean, metabasalt, geodynamic regimes, actualism.
