Objectives

 

Acquisition of theoretical knowledge on the geochemical laws that govern the chemical element distribution in the natural geochemical processes; resolution of practical cases using the treatment of analytical data that allow the characterization of primary evolution and the effectof secondary geochemical processes; understanding the effects of Man activity in the environmental equlibrium based on the study of the  mobility and dispersion of elements.

 

Learning outcomes and competences


 

The student will be able to solve practical exercises and perform an analysis, discussion and critical interpretation of  the results. The theoretical/ practical exercises contribute to acknowledge the importance of the application of the acquired skills, as well as to leave in perspective future developments in the analytical techniques to  face  new geochemical challenges.
