“…The primary magma produced from the decompression melting of the lithospheric mantle, in this period, mixed with the upwelling asthenospheric magma. It can be well verified by the high‐Mg adakite and the other mafic rocks in the same area at a similar time (Guo, Fan, Wang, & Zhang, 2004; Huang et al, 2016; Ma et al, 2014; Tan et al, 2008; Zhang, Zhang, Ying, Tang, & Niu, 2008). Subsequently, the felsic magma that was originated by partial melting of the lower crust resulted from the underplating of the mantle‐derived mafic magma.…”

“…Due to the density difference, the lower mafic crust which contains eclogite can be recycled into the mantle, causing partial melting and reworking of the ancient basement rocks to generate granitic magma (Gao, Rudnick, et al, 2004; Wu, Zhao, Sun, Li, He & Bao, 2013; Xue et al, 2019; Zhao, Isozaki, & Maruyama, 2017). Between 185 and 165 Ma (Figure 12b), lithospheric delamination occurred beneath the Sulu orogenic belt, which provided a channel along the deep lithospheric faults for the asthenospheric upwelling (Huang et al, 2016; Wang, Chang, Wang, Lu, & Zhang, 2015), and triggered the uplift, the orogenic collapse and the lithospheric extension and thinning of the Sulu belt. Furthermore, eclogite has lower melting temperatures than peridotite (Sobolev et al, 2007).…”

Petrogenesis of Cretaceous granites in the southern Sulu Orogen: Implications for the flare‐up of post‐collisional magmatism

To well understand the dynamic mechanism of Cretaceous magmatism flare-up in the southern Sulu Orogen (SSO), the ages and petrogenesis of Qingyun monzogranites and the other coeval granitic plutons in the SSO are investigated herein through an integrated study of petrology, geochemistry, geochronology, and Sr-Nd-Pb-Hf isotopes. The studied granites are characterized by high Si, weak peraluminous, poor Fe and Mg, rich alkaline and high K. They are also characterized by enriched light rare earth element (LREE) and depleted heavy rare earth element (HREE), with the strong fractionation between LREE and HREE [(La/Yb) N = 19.71-45.78]. Besides, the rocks are depleted in HFSEs (i.e., Ta, Nb, Ti, and P) and relatively enriched in Pb and LILEs (i.e., Rb, Th, and K), with moderate negative Eu anomalies (δEu = 0.62-0.72). The lithogeochemical characteristics indicate that they are highly differentiated I-type granite. Zircon U-Pb dating shows the age of monzogranite is 126.7 ± 1.0 Ma, which formed by magmatism in the Early Cretaceous. In addition, all the samples have low (206 Pb/ 204 Pb) i , (207 Pb/ 204 Pb) i , and (208 Pb/ 204 Pb) i (15.927-16.173, 15.356-15.383, and 37.084-37.412, respectively), similar to coeval felsic and mafic rocks from the Sulu Orogen and the North China Craton (NCC). Moreover, they display negative εHf(t) values (−21.53 to −34.43) with T DM2 model ages (2.55-3.35 Ga). Both the εHf(t) and T DM2 model ages indicate that they are derived from partial melting of the NCC Neoarchean continental crust. Therefore, it is believed that the rocks are primarily derived from partial melting of lower crust in granulite facies beneath the moderate pressure (0.8-1.3 GPa), corresponding to a depth of 35-45 km, within an extensional tectonic environment. The mineral fractional crystallization could occur in the diagenetic process. The delamination of lithosphere and the underplating of upwelling asthenospheric magma, which are reinforced by the subduction of the Palaeo-Pacific Plate, could be the main factors to lead to partial melting of lower crust.
