Abstract: Abstract The early Paleoproterozoic represents a period of rapid changes in Earth systems that could have affected the stable isotopic composition of seawater. The well-preserved pillow structures, hyaloclastites and komatiitic basalts of the 2.43–2.41 Ga Vetreny… read more here.

DOI: 10.1016/j.lithos.2021.106248
Abstract: Abstract The Taihua Complex in the Xiaoqinling area of the southern Trans-North China Orogen (TNCO) records extensive magmatism during the early Paleoproterozoic. This contrasts with the tectono-magmatic quiescence recorded globally at this time. Based on… read more here.

Petrogenesis of the early Paleoproterozoic low-δ18O potassic granites in the southern NCC and its possible implications for no confluence of glaciations and magmatic shutdown at ca. 2.3 Ga

DOI: 10.1016/j.precamres.2021.106258
Abstract: Abstract The interval of 2.45 to 2.20 Ga has previously been interpreted to contain a plate tectonic shutdown, but newly discovered magmatism of this stage is filling in the early Paleoproterozoic magmatic gap. However, the crust… read more here.

Neoarchean–early Paleoproterozoic crustal evolution in the Jiapigou terrane in the northeastern part of the North China Craton: Geochemistry, zircon U–Pb dating and Hf isotope constraints from the potassic granitic complex

DOI: 10.1016/j.precamres.2021.106341
Abstract: Abstract Neoarchean granitic rocks are important components of Precambrian cratons, and their petrogenesis can provide constraints for understanding the evolution of continental crust. The Neoarchean potassic granites are widely distributed in southern Jilin Province, which… read more here.
