DOI: 10.1016/j.epsl.2017.02.032
Abstract: Abstract Crustal foundering is an important mechanism in the differentiation and recycling of continental crust. Nevertheless, little is known about the dynamics of the lower crust, the temporal scale of foundering and its role in… read more here.

DOI: 10.1016/j.lithos.2017.06.001
Abstract: Abstract From the Neoproterozoic to the early Paleozoic, the northern Gondwana margin was sequentially shaped by the Cadomian accretionary and the Variscan collisional orogens which offers the opportunity to investigate the relative extent of crust… read more here.

New insights into Neoarchean–Paleoproterozoic crustal evolution in the North China Craton: Evidence from zircon U–Pb geochronology, Lu–Hf isotopes and geochemistry of TTGs and greenstones from the Luxi Terrane

DOI: 10.1016/j.precamres.2019.04.010
Abstract: Abstract Tonalite–trondhjemite–granodiorite (TTG) suites constitute dominant components of Precambrian continental crust and provide important insights into the crustal evolution history of the early Earth. Here we investigate a suite of TTGs and associated greenstones from… read more here.

DOI: 10.1016/j.precamres.2019.105473
Abstract: Abstract Neoproterozoic metavolcanic-sedimentary sequences are well preserved along the southwestern margin of Tarim Craton, NW China. In order to constrain the depositional timing of the metasedimentary sequences and better understand the crustal evolution, we present… read more here.

Abstract: The Cadomian belt (ca. 600–500 Ma) extends from North America through Europe to Iran (Figure 1). It is characterized mainly by eroded, metamorphosed, and deformed magmatic arcs and back-arc basins ... read more here.

Tracing crustal evolution by U-Th-Pb, Sm-Nd, and Lu-Hf isotopes in detrital monazite and zircon from modern rivers

DOI: 10.1130/g38720.1
Abstract: Detrital zircon U-Pb age and Hf isotope studies are useful for identifying the chemical evolution of the continental crust. Zircon, however, is typically a magmatic mineral and thus often fails to document the timing of… read more here.
