文摘

Formation water is 87Sr rich and resulted from cross and lateral formational fluid flow. TSR leads to depletion in SO4 and decrease in δD value of formation water. Formation water may have mixed with paleo-meteoric water and shale-derived water. Oils and hydrothermal water may have migrated along similar pathways.
