Learning objectives

<br />To deepen in the laboratory the working of all the stable isotope ratio facilities located in the Earth Sciences Department at the University of Parma. It is addressed mainly to students who want to make a research thesis on isotope geochemistry for hydrological, palaeoclimatological, environmental, petrological, archaeological purposes.
