Objective
To know the conditions of formation, the atomic structure, classification, reactivity and stability conditions for secondary minerals common in soils. To know the techniques to identify them, fromt pre-treatment of samples to interpretation of XRD results.
Content
This course introduces the main soil minerals, including their chemical and genetic aspects. The focus is in minerals in the soil clay fraction of tropical and subtropical soils. Unit 1- Introduction. Use of soil mineralogy information in soil science areas to address practical problems. Unit 2 - Crystalloraphy basics. 3- Conditions for secondary clay minerals formation and stability. Unit 4 - 1:1 Phyllosilicates. Unit 5- 2:1 Phyllosilicates. Unit 6- Iron and Aluminum Oxides. Unit 7 - Primary minerals in soils. Unit 8 - Relationships between mineral structure and physical-chemical behavior of mineral soils. Unit 9- Methods of sample preparation. Unit 10- Basic techniques of mineral identification in soils, with emphasis in X ray diffraction.
