A steady-state Sr model of the ocean, containing: Volcanic islands + basalt-derived Sr with low radiogenic and stable Sr isotopic composition; and CaCO3 dissolution from sediments and below the lysocline.
The carbonate dissolution has an oceanic radiogenic and stable Sr isotopic composition, which is delayed by Ξπ.Β Sr co-deposition with CaCO3 is a linear function of the oceanic Sr inventory.Β Includes Sr input to the ocean from dissolution of dust CaCO3.Β
