Archean-Mesoproterozoic Crustal Evolution and Crust-Mantle Geodynamics of Western Liaoning-Northeastern Hebei Provinces, North China Craton

Meer over het boek

The thesis explores the geological and petrological characteristics of Precambrian lithologies in the Western Liaoning-Northeastern Hebei Provinces, focusing on various rock types from late Neoarchean to late Paleoproterozoic eras, including metavolcanic rocks and alkaline plutons. It investigates the sources of magma and the genesis of magmatic episodes, while also establishing the evolution of the lithospheric mantle and crust-mantle interactions from approximately 2.6 to 1.2 billion years ago, offering significant insights into the region's crustal evolution and geodynamic processes.
