Volatile emissions to the atmosphere associated with Siberian Traps eruptions at Permian-Triassic boundary were sourced from outgassing of primary magmas and sedimentary host rocks into which they intruded. Halogens in volcanic gases may have played an important role environmental degradation stratospheric ozone destruction. Here we investigate how halogens behave during interaction between sal...

Large volume of evaporites were deposited during the Messinian Salinity Crisis (MSC) across Mediterranean. These are currently outcropping on land and interpreted by seismic profiles beneath Mediterranean floor. Biostratigraphic, magnetostratigraphic astrochronologic data recovered from sediments below above evaporites, together with gypsum facies associations stratigraphic cyclicity, cornersto...

Evaporites are widely distributed within continental “red beds” in the Lanping–Simao Basin, west Yunnan, China. Sr (Strontium), S (Sulfur), and O (Oxygen) isotope compositions have been measured on 54 sulfate or/and sulfate-bearing samples collected from Lanping, Nuodeng, Jinggu, Mengyejing, Baozang throughout Basin. The 87Sr/86Sr ratios of all (0.708081 to 0.710049) higher than those contempor...
