| Contenuti | Il Corso di Laurea Magistrale in Geologia degli Idrocarburi mira a fornire un'approfondita e specializzata formazione culturale e tecnico-professionale finalizzata al reperimento e utilizzo sostenibile delle risorse del sottosuolo, con particolare riferimento all’esplorazione e modellazione dei sistemi naturali petroliferi ed a gas. L'obiettivo finale e` quello di fornire allo studente, a partire da una solida preparazione generale nei settori della stratigrafia, della sedimentologia e della tettonica, la possibilità` di acquisire gli strumenti culturali, la preparazione professionale e la capacita` di analisi critica necessari per l'inserimento nel mondo dei servizi di esplorazione, anche attraverso esperienze di lavoro sperimentale in campagna e in laboratorio. |
