Title
Stable isotopes of strontium as a new proxy for continental weathering, pedogenesis processes and seawater temperature
General information
Identifying the modes of traditional radiogenic strontium isotope ratios (87Sr/86Sr-Norm) and of non-traditional stable strontium isotope fractionation (δ88/86Sr) in continental weathering products as well as in marine calcium carbonate is critical for interpreting the chemical and climatic history of the Earth. Following this approach a group of Palestinian, Israeli and German scientists initiated the TRION project to test the application of paired radiogenic and stable Sr isotopes (87Sr/86Sr*-δ88/86Sr) for their potential to study continental weathering processes and biomineralization pathways as well as to determine the degree of temperature and rate dependent Sr isotope fractionation during the precipitation of organic and inorganic carbonates. This will extend and complete the conventional applications of the radiogenic Sr isotope ratios (87Sr/86Sr-Norm) in the field of the environmental and geosciences. Beyond the scientific goal, the TRION project is expected to contribute to the peace process in the Middle East by actively generating scientific communication, collaboration and sustainable networking among scientists from the Palestinian Authority and Israel. In order to achieve this societal goal TRION project is extended by a program of education and training for a group of joint Palestinian, Israeli and German students, sustainable capacity building and public outreach.
