Sulfur isotope composition in the Plesenci native sulfur mineral deposit, Republic of Macedonia [PDF]
, 2015 For the first time, we present our findings of the origin of sulfur in the gypsum and native sulfur within the Plesenci deposit, R.Macedonia. There we made a series of complex research and analysis of the light isotope (32S), heavy isotope (34S), and ...

Sulphur-isotope compositions of pig tissues from a controlled feeding study [PDF]
, 2017 Sulphur-isotope determinations are becoming increasingly useful for palaeodietary reconstruction, but knowledge of isotopic discrimination between diet and various tissues remains inadequate. In this study, we explore the sensitivity of δ34Stissue values

Sulfur isotope rations of sulfide minerals from the deposit of the Tsuchikura mine, Shiga Prafecture, Japan [PDF]
, 1998 Sulfur isotope rations of sulfide minerals in the ore specimens from the deposit of the Tsuchikura mine are distrib-uted in a range from -0.8 to 5.4%, mostly from +0.5 to 3.0%, close to the previous data (from +1 to +3%) by Miyake and Sasaki (1980).

Constraining the rise of oxygen with oxygen isotopes
Nature Communications, 2019 The loss of anomalous sulfur isotope compositions from sedimentary rocks has been considered a symptom of permanent atmospheric oxygenation. Here the authors show sulfur and oxygen isotope evidence from

Sulphur and Carbon Isotopes as Tracers of Past Sub-seafloor Microbial Activity [PDF]
, 2019 Microbial life below the seafloor has changed over geological time, but these changes are often not obvious, as they are not recorded in the sediment.
