The mixed model shows that the ratio of sulfur isotopes in rock sources gradually increases from A to C, while the ratio of sulfur isotopes in seawater sources gradually decreases
The mixed model shows that the proportion of sulfur isotopes in rock sources increases gradually from area A to c, while the proportion of sulfur isotopes in sea sources decreases gradually.
