According to the vertical variation, paleosalinity is divided into four stages (Fig.
Many researchers have reconstructed paleosalinity and paleotemperatures through analysis of carbon and oxygen isotopes.
18]O + 50), where Z represents paleosalinity, carbon and oxygen isotopes can be analyzed together to indicate relative paleosalinity .
Paleoclimate may have been controlled by difference between paleosalinity and salinity of water rich in certain ions .
In its second and fourth stages, salinity was favoured by the extrapolated paleoclimate characteristics, in relatively hot and arid climate conditions paleosalinity was higher and in relatively humid climate conditions paleosalinity was lower.
Previous researches showed that the distribution of illite and kaolinite from continent to sea is connected with paleosalinity of water [32, 33].
