Archean crustal evolution in the northern Yilgarn Craton: U–Pb and Hf-isotope evidence from detrital zircons

The Paleozoic tectonic evolution and metallogenesis of the northern margin of East Junggar, Central Asia Orogenic Belt: Geochronological and geochemical constraints from igneous rocks of the Qiaoxiahala Fe-Cu deposit

“…398-385 Ma; Griffin et al, 2004). The Devonian age is consistent with the oldest intrusions reported in the Beitashan Formation, including SHRIMP U-Pb zircon ages of 381-376 Ma and LA-ICP-MS zircon U-Pb ages of 393-375 Ma (Xiang et al, 2009;Zhao et al, 2009;Lu et al, 2012;Yang et al, 2012;Li et al, 2014), indicating that the Beitashan Formation was formed older than ca.…”

Episodic crustal growth in the southern segment of the Trans-North China Orogen across the Archean-Proterozoic boundary

“…The single-stage Hf model ages (T DM-Hf ) refer to extraction from a depleted mantle (Supplemental Table 3; Fig. 4), whereas the "crustal" model ages (T DM-Hf C ) are calculated by assuming the parental magma was produced from average continental crust ( 176 Lu/ 177 Hf = 0.015) that was originally derived from the depleted mantle (Griffin et al, 2004).…”

Two tales of the continental lithospheric mantle prior to the destruction of the North China Craton: Insights from Early Cretaceous mafic intrusions in western Shandong, East China

“…Two-stage model ages (T DM2-Hf ) are calculated by assuming formation from average continental crust ( 176 Lu/ 177 Hf = 0.015) that originally was derived from the depleted mantle (Griffin et al, 2004 Pb ages. Province (Fig.…”
