Compositional data: analytical approach and final aims. Fluids from volcanic, and hydrothermal environments. Volcanic monitoring and geothermal prospection. Fluid composition from primary sources and secondary processes. Geochemical tracers. Isotopes of noble gases and greenhouse gases. Limnology. Volcanic lakes. Origin and behaviour of volatile organic compound. Environmental impact of natural and anthropogenic pollutans.
Power point presentations. Scientific papers published by international journals.
Learning Objectives
The main objective of the course is to provide to the students tools for the study of the behaviour of fluids from natural and anthropogenic environments. A further objective is to provide to the students tools for classification of natural and anthropogenic fluids based on chemical and isotopic parameters.
Prerequisites
no
Teaching Methods
Power point presentations. Fieldtrips (Aeolian Islands, Mt. Amiata)
Further information
6CFU Attending the course is not mandatory but highly recommended.
Type of Assessment
Oral exam: the student should answer to several questions related to the main topics of the course. The critical capability of the course topics will be evaluated.
Course program
The course provides basic concepts of geochemical processes regulating the chemical and isotopic composition of fluids from natural (volcanoes, geothermal systems, thermal areas) and anthropogenic environments. The main potential primary sources of fluids are investigated, as well as the effects on their chemistry of secondary processes. The course will take into account the behaviour of environmental tracers for themes concerning 1) contamination of air and natural waters, 2) the use of geochemical parameters for geothermal prospection and volcano monitoring, 3) geochemical-biological processes controlling geochemical features of volcanic lakes.
Several examples (key studies) from volcanic and urbanized areas will be shown.
