Fig. 4: Sulfur isotope degassing under different eruption (effusive and explosive) and impact conditions.
From: Sulfur isotopes from the lunar farside reveal global volatile loss following the giant impact
The modeled curves (brown dashed lines) with different P/PSat (effective vapor pressure relative to saturation pressure) are based on the lunar sulfur isotope degassing model from Gargano et al.29 and Saal and Hauri46 using an initial δ³⁴S value of 0.6‰ and an initial sulfur content of 2500 μg/g (a). In (b), the red shaded area denotes the δ³⁴S and sulfur content range observed in CE-6 basalts. The δ34S values of CE-5 and Apollo mare basalts are from the literature8,28,29 and references therein. Data for impact glasses and lunar soils are from the literature32 and references therein, while volcanic glass data are sourced from the ref. 46.
