GEOV210 Plate Tectonic
|
Objectives and Content:
From a geological perspective, we may consider the Earth¿s outer part to be made up of isolated entities with dynamically active perimeters and large relative horizontal movements. The course presents an introduction to the physical criteria used to define the horizontal and vertical dimensions of the plates and how we can directly measure plate surface motion today and in the geologic past. The course describes the most important geological processes taking part in the three principal types of plate boundaries and demonstrates the connection to large scale geological structures below the oceans and dynamics of mountain building on the continents. Learning Outcomes: After completion of the course GEOV210, the student should be able to: - describe the characteristics of a geological plate - explain the methods which are used to document relative plate motion - describe the most important geological processes at the plate boundaries - analyse large scale geological events such as rifting of continents and formation of mountain chains in light of plate tectonic movements. Required Previous Knowledge: Principles of geology and physics of the earth. Forms of Assessment: Written, 4 h |

GEOV242 Igneous and Metamorphic Petrology
|
Objectives and Content
The course reviews igneous activity in different plate-margin environments, including continental rifts, oceanic spreading ridges, subduction zones and continental collision zones as well as within tectonic plates. An introduction is given to the processes that lead to the formation of magma in the Earth's mantle and crust, processes that modify magma and processes that take place during the crystallisation of igneous rocks. The mineralogical and textural changes that take place in ordinary crustal rocks under different metamorphic conditions, for instance around shallow igneous intrusions, at spreading ridges, in subduction zones and during continental collisions, are also described Learning Outcomes On completion of the course a student should be able to: - Explain the formation of magma by partial melting of mantle and crustal rocks. - Give an account of magmatic differentiation, hybridisation and contamination. - Give an account of the connection between the nature of magmatic activity and the plate-tectonic environment. - Interpret simple geochemical variation diagrams for igneous rock series. - Describe and interpret the textures of igneous and metamorphic rocks. Required Previous Knowledge Basic principles of mineralogy and petrography, as well as knowledge in microscopy Forms of Assessment Grading of student portfolio |

GEOV342 Radiogenic and Stable Isotope Geochemistry
|
Objectives and Content
This course provides an introduction to the principles of radiogenic and stable isotope geochemistry, and to the application of isotopes in geological studies. The radiogenic isotopes (e.g., Rb/Sr, Sm/Nd and U-Th-Pb) and their geological applications will be reviewed in the first part of the course. The second part of the course deals with the stable isotopes (such as H, O, C, N). The factors that control the distribution and fractionation of stable isotopes in natural systems and their application in paleoceanography and paleoclimatology will also be reviewed. Learning Outcomes On completion of the course GEOV342 a student should: - understand the geological problems that can be solved by isotope methods. - have the adequate background for the application of isotopes in geological studies. Required Previous Knowledge Basic principles of sedimentology, palaeoceanography and palaeoclimatology. Forms of Assessment Written assignment |
