Abstract: Abstract We report for the first time magmatic Ca-rich (CaO = 7–11.3 wt%) almandine garnet-bearing ferroan granites. The almandine (Alm66.6Grs24.2Pyr4.9Spes3.9Uvr0.1) garnet-bearing Tilaboni granite pluton was emplaced in a major regional shear zone of Chhotanagpur Gneissic Complex, Eastern India.… read more here.
