Geochemical Records Linking Plate Tectonics with Mantle Dynamics: Neoproterozoic and Beyond
MetadataShow full item record
This Ph.D. thesis investigates Earth’s dynamic evolution through geological time by addressing possible linkages between the evolution of the Earth’s mantle and crustal growth, plate tectonics, and superplume-supercontinental cycles. This is achieved through deciphering the geochemical records of mantle-derived/related rocks that characterised the Earth’s mantle evolution and processes at global-, regional- and micro- to nano-scales.
