Objective
Provide students with the basic and fundamental concepts on the geochemistry of weathering and pedogenetic processes in the main geochemical environments of the pedosphere. Provide basic elements for predicting the formation, stability and alteration of soil minerals. Bring basic information about the geochemical processes of pedogenesis, from the alteration of rocks to the formation of different soils.
Content
1. Introduction and historical evolution of geochemistry. 2. Structure and composition of the Earth. 3. Interaction of different geochemical spheres: atmosphere, biosphere, lithosphere and hydrosphere. 4. The pedosphere and the concept of Critical Zone. 5. Geochemistry of weathering reactions. 6. Conditions for formation, balance and alteration of the main secondary minerals in soils. 7. Geochemistry of active pedogenetic processes in the hydrolytic, acidolytic, hydromorphic and halomorphic domains and considerations about their soils. 8. Living beings as forcings in the geochemistry of pedogenesis. 9. Research practices in soil geochemistry: case studies. 10. Geochemical modeling applied to soil science.
