Summary
Automatically generated
Analyses van de zwavel isotopensamenstelling (δ34van S) van pyriet van methaan-bevattende sedimenten hebben meestal gericht op laboratoriummonsters. Hier, pasten we secundaire ion massaspectrometrie voor het analyseren van de δ34S-waarden van verschillende generaties van pyriet te begrijpen van de diagenetic geschiedenis van pyritization.
