Mesoarchean gabbro-anorthosite complex from Singhbhum Craton, India

The Singhbhum Craton in Peninsular India preserves some of the oldest continental crust on the globe with Hadean and Paleoarchean zircon record. Here we investigate a gabbro-anorthosite complex from the eastern margin of the craton exposed at Besoi, Kuliana, Sarat and Jashipura areas. These rocks display moderate SiO2 (47.94–53.77 wt%), TiO2 (0.42–2.17 wt%), Al2O3 (8.97–14.96 wt%) MgO (6.14–10.30 wt%) and CaO (10.73–15.07 wt.) at low to moderate...
