摘要
Archean crustal terranes are commonly featured with the dome–and–keel structures,in which supracrustal rocks occur as belts(greenstones)between,and rafts within,dome-like bodies of tonalite–trondhjemite–granodiorite(TTG).Supracrustal rafts within TTG gneisses generally record metamorphic grades ranging from amphibolite-to ultra-high temperature(UHT)granulitefacies of low-to moderate-pressure conditions[1].Notably,granulite-facies rafts commonly show counterclockwise P±T paths involving a significant increase in pressure at high temperatures[2,3].However,the tectonothermal drivers behind such metamorphism are still debated.
