Abstract: Abstract Isotopic compositions of coeval sulfide and sulfate have been widely employed to reconstruct the seawater chemistry evolution over geologic time; however, these signals can be modulated by other factors, such as the sedimentation rate.… read more here.

DOI: 10.1016/j.oregeorev.2021.104260
Abstract: Abstract The Gouli goldfield is the most important gold producers of the East Kunlun metallogenic belt. Gold mineralization in this region is enigmatic, primarily because of uncertainties as to the mineralization processes, and the nature… read more here.

DOI: 10.1126/sciadv.1701835
Abstract: Neoarchean S isotopes indicate protracted ocean oxygenation and sulfate buildup under anoxic atmosphere. Abrupt disappearance of mass-independent fractionation of sulfur isotopes (MIF-S) from the geologic record and an apparent ingrowth in seawater sulfate around 2.45… read more here.
