2007-2008.4, Central Geological Survey Project: Tracing sediment source in Shihmen water reservoir using strontium isotopes

Research Highlight

The global climatic change and continental weathering is a complex cause-consequence feedback system. Non-traditional isotope systems offer a new potential chance for better understanding the biogeochemical reactions in exogenic processes and/or be used as a new tracer for weathering sources. My current research utilizes the triple Sr isotopes (87Sr/86Sr & δ88Sr) to evaluate the Sr cycles in continental weathering systems and involved weathering processes. These results will form a background for interpreting the link between continental weathering and the climatic evolution in the past.
