Therefore, we interpret the enrichment in Sr isotope ratios in Kalana barite to represent the excess radiogenic Sr derived from the alteration of silicates (e.
1999), which could be due to: i) riverine input of radiogenic Sr produced by weathering of continental silicate; ii) Sr derived from hydrothermal circulation produced at mid-ocean ridges (Faure, 1986), likely coincident with second-order sea level fluctuations (Gaffin, 1987).
