Geochronological and isotopic constraints on Neoproterozoic crustal growth in the Egyptian Nubian Shield: Review and synthesis
The tectonic evolution of the Neoproterozoic Arabian-Nubian Shield (ANS) is widely held as
an example of crustal growth processes. The ANS consists of continental crust formed prior …

Magmatic degassing and fluid metasomatism promote compositional variation from I-type to peralkaline A-type granite in the late Cretaceous Fuzhou felsic complex …
F Zhang, F Guo, X Zhang, L Zhao - American Mineralogist, 2024 - degruyter.com
A-type granites generally have much lower water, higher temperature, and incompatible
element concentrations than I-type granitoids. Yet it remains unclear why IA-type granitic …
