摘要: The hemispheric impact of industrial emissions upon atmospheric sulphur loading is reflected in the depositional history recorded cores from ice sheets. However, these do not reveal regional variations. Recently deposited speleothems are used here as archives at two locations within United Kingdom and Ireland. δ34S-so4 δ18O-so4 present speleothem carbonate measured for first time part a dual isotope approach to decode record. largely refractory nature under oxidising conditions enables source provenance SO2, whereas complex cycles isotopic exchange fractionation during incorporation oxygen into sulphate molecules enable signatures yield insights ambient environmental biogeochemical cycling ecosystem above cave. values extracted formed Browns Folly Mine, UK, range +3.5 +5.5‰ +10.3 +13.7‰. Both lie expected deposition reflect transfer calcite with little fractionation. Crag Cave, western Ireland, isotopically heavier than equilibrium δ18O-h2o reducing conditions. Dual analysis optimises correct identification sources prior At carefully selected cave sites where drip water flowpaths remain oxic, hold potential retain records local scale.
