Sanukitoid rocks make up a complete magmatic series with distinct geochemical characteristics of TTG suites and granitoids from modern arcs are regarded as markers the transition typically Archean geodynamics to plate tectonics. Although most known sanukitoid formed during Neoarchean Mesoarchean, numerous papers have characterized Paleoproterozoic arc granitoid showing affinity series. This wor...
