Two-stage granulite formation in a Proterozoic magmatic arc (Ongole domain of the Eastern Ghats Belt, India): Part 2. LA-ICP-MS zircon dating and texturally controlled in-situ monazite dating

To quantify the Mesoproterozoic pressure–temperature–time evolution of the granulite-facies Ongole domain, a deep crustal Proterozoic magmatic arc in the Eastern Ghats Belt, LA-ICP-MS U–Pb zircon dating and in-situ electron microprobe U–Th–total Pb monazite dating are integrated with the petrologic observations. Zircon grains in the metapelites often preserve oscillatory-zoned, sometimes partly resorbed cores yielding a spread of 207Pb/206Pb...
