“…Zheng et al (2005Zheng et al ( , 2019 divided the Dabie orogen into five main tectonic units (Figure 1d). These are from north to south: the Beihuaiyang terrane (a LT-LP greenschist-amphibolite-facies metamorphic belt, T = 570°C, P = 0.71 GPa), the north Dabie terrane (a HT-UHP eclogite-facies metamorphic belt, T = 875°C, P = 4.50 GPa), the central Dabie terrane (a MT-UHP eclogite facies metamorphic belt, T = 613-728°C, P = 3.09-3.87 GPa), the south Dabie terrane (a LT-(U) HP eclogite-facies metamorphic belt, T = 600-630°C, P = 2.70-2.90 GPa) (Xia et al, 2023) and the SuSong Complex (a LT-HP blueschist−greenschist-facies metamorphic belt, T = 427-532°C, P = 0.34-0.98 GPa) (Wu et al, 2023). All five zones are intruded by a voluminous suite of Early Cretaceous granitic plutons (Figure 1d; Jahn et al, 2003;Zheng et al, 2019), with minor occurrences of coeval volcanic rocks (Fan et al, 2004).…”
