VOLCANO-TECTONICS

GEO/03 - 6 CFU - 2° semestre

Docente titolare dell'insegnamento

GIORGIO DE GUIDI

Obiettivi formativi

The student at the end of the course:

- He will be able to analyze and interpret: on a regional and local scale, geological, morphological, geophysical and geodetic data in areas affected by volcano-tectonic processes;

- Sarà pertanto in grado di rilievare geostrutture ricollegabili ad attività tettonica e vulcanica, definire le interrelazioni tra geometria, cinematica e dinamica di origine tettonica e vulcanica nonché valutare l’ordine di grandezza spazio-temporale dei distinti geoprocessi;

- Sarà in grado di pianificare con metodologia multidisciplinare lo studio vulcano-tettonico di domini interessati da vulcanismo in differenti contesti tettonici, ed esporne i contenuti con linguaggio tecnico appropriato

Modalità di svolgimento dell'insegnamento

"42 ore (6 CFU) di lezioni frontali” - 42 hours (6 CFU) teacher-led discussion

Prerequisiti richiesti

La conoscenza dei processi geodinamici, Tettonica globale, strutture tettoniche attività sismica e vulcanica, domini tettonici di tipo collisionale, di subduzione, rift continentali, meccanismi di deformazione fragile e duttile, Tettonica e geomorfologia

Frequenza lezioni

FREQUENZA LEZIONI: obbligatoria. Lo studente dovrà frequentare almeno il 70% delle lezioni (lezioni frontali e/o laboratorio). Il docente verificherà la presenza in aula e compilerà un registro delle presenze.

Contenuti del corso

This course combine results frackture mechanics, rock mechanics structural geology, hydrology, and fluid transport in the crust to explore and explain fracture processes and fluid transport in the crust. Basic concept are developed for first principlesand are illustrated with numerous worked examplesthat link models of volcano tectonics processes to real field observations and measurements.

Verifica dell'apprendimento

MODALITÀ DI VERIFICA DELL'APPRENDIMENTO

Concept evaluation remains a fundamental tool so that to comprehend the origin of the obstacles faced by students while their learning of the concept of volcano-tectonics. Many verify methods can be used such as a questionnaire, an interview, observation, and other methods: In this course, we chose all of these as a evaluation tool. On the one hand, this choice is designed to have a more comprehensive view on students' conceptions, but also to give them the freedom to respond and choose elements they deem correct answers.
