Abstract:
The carbonate cements found in Sites 717-719 of ODP Leg 116 correspond to the precipitation of inorganic calcite due to circulation of hot fluid associated with intraplate deformation in the central Indian Ocean. A first burst of hydrothermal activity may have occurred 7.5-9 Ma and a second burst less than 0.5 Ma. These fluids were probably derived from the basaltic basement and the immediately overlying sediments.
