Diverse P–T paths of the northern Dabie complex in central China and its reworking in the early Cretaceous

Multiple episodes of anatexis in a collisional orogen: Zircon evidence from migmatite in the Dabie orogen

“…The early Cretaceous ages were also obtained from granulite at Huilanshan (Hou et al, 2005). These early Cretaceous magmatic and metamorphic ages support the notion that the widespread magma emplacement and HT granulite-facies metamorphism in the North Dabie zone are associated with contemporaneous migmatization (Tong et al, 2011), suggesting extensive anatexis in the early Cretaceous.…”

“…Accordingly, four metamorphic stages are recognized in the North Dabie zone (Liu et al, 2007a(Liu et al, , 2011a(Liu et al, , 2011bTong et al, 2011): (1) an UHP eclogite-facies stage, with P = 2.5-4.0 GPa and T = 800-980 °C, witnessed by the occurrence of diamond;…”

P-T evolution of elusive UHP eclogites from the Luotian dome (North Dabie Zone, China): How far can the thermodynamic modeling lead us?

“…From north to south, the Dabie orogen is divided into five, fault-bounded, major lithotectonic units (e.g. Liu et al, 2007a;Tong et al, 2011;Xu et al, 2003;Zhang et al, 2009): (i) the low-grade Beihuaiyang Zone (BZ); (ii) the high-T migmatitic North Dabie complex Zone (NDZ); (iii) the Central Dabie UHP metamorphic Zone (CDZ); (iv) the South Dabie low-T eclogite Zone (SDZ); and (v) the Susong complex Zone (SZ) (Fig. 1a).…”

High‐pressure granulite facies re‐equilibration and zoisite–biotite dehydration melting during decompression of an ultrahigh‐pressure garnet clinopyroxenite from the island of Fjørtoft, Norway

“…Cao et al, 2019; Liu, Massonne, et al, 2020; Liu et al, 2015; Massonne, 2001, 2012; Walsh & Hacker, 2004). Alternatively, modification can result from granulite facies overprinting that is commonly reported for relatively hot rocks that previously experienced eclogite facies conditions (e.g., Butler et al, 2013; Cao et al, 2019; Haifler & Kotková, 2016; Nakamura & Hirajima, 2000; Song et al, 2014; Štípská et al, 2014; Tong et al, 2011; Yao et al, 2000). Granulite facies overprinting can reset early eclogite facies parageneses more efficiently (owing to faster reaction kinetics), compared with resetting at lower grade conditions, and may lead to the total loss of information on the metamorphic pressure peak (e.g., Dong et al, 2019; Engvik et al, 2018; Faryad & Cuthbert, 2020; Haifler & Kotková, 2016).…”
