COURSE TITLE: Ophiolites: Production and destruction of oceanic crust
LECTURERS: Prof. J. Hermann
SCOPE:
HELD AT:BE
CATEGORY:
ECTS Credits:2.5
PREREQUISITES:
REQUISITES:
FORMAT:Lecture and exercises
FREQUENCY:biennially in fall semester, held in odd years
CONTENTS:Ophiolites are remnants of former oceanic crust and they provide insight into fundamental aspects of plate tectonics. In exhumed ophiolite sequences oceanic crust formation can be investigated through composition, temporal evolution and the three dimensional distribution of mantle rocks, gabbros, basalts and sediments. Ophiolite sequences in mountain belts often preserve relics of high-pressure metamorphism that allow insights into processes acting in subduction zones, where oceanic crust is transported back into the mantle. In this course theoretical concepts will be combined with case studies to investigate the petrology, mineralogy and geochemistry of oceanic crust formation and recycling of elements through subduction zones. The course will combine, lectures, practical work as well as some presentations. By the end of this course the participants will have (1) knowledge of key processes responsible for formation and subduction of oceanic crust (2) apply theoretical concepts to the interpretation of oceanic rock suites and (3) evaluate relevant literature critically. There is no formal prerequisite for this course (basic knowledge in petrology and geochemistry is expected). Students taking this course will have preference on the Liguria excursion in the following semester. This course is part of a two-year sequence involving the courses volcanism, volcanic excursion, ophiolites, Liguria excursion.
ASSESSMENT:Presentation
SPECIALITIES:EM, GEOL
