Abstract
⺠The ca. 2.7 Ga leucogranitoids were mainly derived from local TTGs. ⺠The compositional scatter, in both major and trace-elements is considerable. ⺠Melting was caused by thickening of the crust in response to collisional tectonics. ⺠Melting occurred under water-fluxed conditions. ⺠Potential fluid sources are lower crust and late mantle derived intrusives.
