“…2.45–2.49 Ga. Such a relatively close timing between arc magmatism and collisional metamorphism has been reported from several other Archean terranes (e.g., Yu, Santosh, Amaldev, & Palin, 2021).…”

“…The khondalite rocks, represented by sillimanite-garnet-graphite gneisses and granulites are present in several Precambrian high-grade terranes. The khondalite protoliths were deposited either in cratonic passive margins (Condie, Boryta, Liu, & Qian, 1992;Xia, Sun, Zhao, Wu, & Xie, 2009;Zhao et al, 2010) or in active continental margins (Barbey et al, 1982;Daly et al, 2001;Wang, Li, & Han, 2018;Yu, Santosh, Amaldev, & Palin, 2021). In NE Brazil, the Ceará Khondalite Belt is limited by migmatitic orthogneisses related to Palaeoproterozoic and Neoproterozoic magmatic arcs.…”

“…Southern Kerala region at the southern tip of Peninsular India (Figure 1a) forms part of the Southern Granulite Terrane (SGT) and incorporates Palaeo-to Neoproterozoic basement rocks belonging to the Trivandrum and Nagercoil blocks amalgamated to the Madurai Block along the Achankovil Suture Zone (ACSZ) (Clark et al, 2015;Collins et al, , b, 2014Liu et al, 2016;Rajesh et al, 2004;Rajesh & Arai, 2006;Rajesh, Arai, & Satish-Kumar, 2009;Santosh et al, 2006,b;Santosh et al, ,b, 2015Santosh et al, , 2017Taylor et al, 2014;Zhang & Santosh, 2019). The SGT is a collage of crustal blocks ranging in age from Mesoarchean to Neoproterozoic (Santosh, 2020;Yu, Santosh, Amaldev, & Palin, 2020), and the latest granulite-facies metamorphism ranged up to ultrahigh temperatures at P-T conditions of 6-8 kbar and up to 950 C during Late Neoproterozoic-Cambrian, associated with the final assembly of the Gondwana supercontinent (Geological Survey of India, 1995;Harley & Nandakumar, 2014;Harley & Santosh, 1995;Rajesh et al, 2004;Rajesh & Arai, 2006, Rajesh et al, 2009Santosh, Yokoyama, Biju-Sekhar, & Rogers, 2003;Santosh, Collins, Morimoto, & Yokoyama, 2005;Santosh et al, ,b, 2015Santosh et al, , 2017.…”
