Sulfur isotopes in Finnish nickel-copper occurrences [PDF]

Bulletin of the Geological Society of Finland, 1980
The sulfur isotope composition of the Hitura, Kotalahti and Kylmäkoski Ni-Cu ores was analyzed. The results have been compared with earlier sulfur isotope analyses of the Vammala, Laukunkangas and Oravainen Ni-Cu occurrences. Altogether 183 analyses were

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 ...

Tetrathionate and Elemental Sulfur Shape the Isotope Composition of Sulfate in Acid Mine Drainage

Frontiers in Microbiology, 2017
Sulfur compounds in intermediate valence states, for example elemental sulfur, thiosulfate, and tetrathionate, are important players in the biogeochemical sulfur cycle.
