Paleoproterozoic tectonic-magmatic evolution in the nucleus of the Yangtze Craton

The Huangling Dome exposed in the nucleus of the Yangtze Craton is an ideal window for exploring the formation and evolution in the Precambrian continental crust of the craton. This paper summarized the research achievement on zircon U-Pb geochronology, Hf isotope and geochemical features of the Paleoproterozoic magmatic rocks in the nucleus of the Yangtze Craton, and discussed the nature, petrogenesis and tectonic setting of these rocks, so as to constrain the geodynamic and tectonic evolution processes in the nucleus of the Yangtze Craton during Paleoproterozoic. It is concluded that the Paleoproterozoic tectonic-magmatic evolution can be divided into four processes, namely the subduction and accretion, uplift and erosion, high-grade metamorphism, and orogenic collapse, which are associated with three stages: oceanic subduction, arc-continent collision, and post-collisional extension.
