The North Qinling (NQ) orogen includes extensive Devonian magmatic rocks (Wang et al., 2013), primarily consisting of I-type granites with fairly lower A-type granite proportions (Han et al., 2021; Ren et al., 2021).Some I-type granites exhibit similar geochemical characteristics to those of adakites (Qin et al., 2020).Based on previous …

Light δD apatites reveal deep origin water in North China …
Introduction. Water is essential for partial melting of the continental crust (CC) to produce granites 1, 2.There are two dominant mechanisms for water supply in this process: decomposition of hydrous minerals in the CC and external water fluxing into melting system 3.Recent studies suggest water-fluxed crustal melting is the primary drive to produce …
