英文摘要	The present study reports trace elemental data from 39 Paleoarchean (3.43 and 3.25 Ga) zircons separated from quartzite near Girar, which forms a part of the South Bundelkhand Supracrustal Complex in Central India. The zircons are prismatic, have well-developed oscillatory zoning and their Th/U ratio ranging from 0.27 to 8.62 is comparable to that of typical magmatic zircons. Crystallization temperature of 620-776 degrees C using titanium-in-zircon thermometer, positive slope of zircon REE patterns, positive Ce anomalies along with mineral inclusions like quartz, muscovite, magnetite and monazite suggest a granitic source for these quartzites. Sm-Nd isotopic data (T-DM age = 3.29 Ga) along with zircon trace elemental data indicate the presence of granitic continental crust in southern Bundelkhand Craton at least during the Paleoarchean (3.4 Ga).; RFBR [15-35-50162, 17-55-45005]; Institute of Geology Karelian RC RAS; School of Earth and Space Sciences, Peking University; SCI(E); ARTICLE; 4; 794-801; 112
