KurzbeschreibungFormation and evolution of the solar system from a geochemical perspective
LernzielTo understand the formation and evolution of the solar system and its planets from a geochemical perspective
InhaltThe Sun and solid objects in the solar system (planets, comets, asteroids, meteorites, interplanetary dust) are discussed from a geochemical perspective. What does their present-day composition tell us about the origin, formation and evolution of the solar system? The lectures introduce the basics of the terrestrial and giant planets, comets and asteroids, gained from modern space missions and the study of extraterrestrial materials. The chemical and isotopic composition of meteorites, being the most primitive material available for study, is a further major topic.

Kurzbeschreibung
LernzielThe purpose of this lecture is to provide a comprehensive overview of: a) the different radiometric methods in Geology, the different dating tasks and the constraints put by the complexity of natural systems, including dating by cosmogenic nuclides,
b) the various analytical tools available today for radiometric dating, their advantages and disadvantages,
c) the use of noble gases in Geochemistry and
d) detailed description of case studies, as examples of approach of a number of geological problems and interpretation of the data.
InhaltThe content of this lecture is summarised as follows:

Anthi Liati:
- Ion microprobes - U-Pb SHRIMP dating (zircon, sphene, rutile, monazite)
- Dating metamorphic rocks
- Combined geochronology and petrology – subduction and exhumation rates
- Tracing the timing of mantle and crustal events via zircon-dating in mantle xenoliths: Two case studies: South Namibia, Kilbourne Hole (New Mexico)

Henner Busemann:
- Noble gas geo- and cosmochemistry
- Surface exposure dating with cosmogenic nuclides
- carbon-14 dating and U-Th-He thermochronology
- Visit of the radiogenic and noble gas isotope laboratories of IGMR

Albrecht von Quadt:
- Analytical tools and applications to radiogenic isotopes (basics about TIMS, LA-ICP-MS-MC)
- Dating magmatic rocks and ore deposits (porphyry, epithermal Cu-Au-(Mo) deposits)
- U-Pb, Re-Os, Pb-Pb methods - Hf tracing of zircons
- Geochronology and geochemistry of magmatic systems

Marcel Guillong:
- LA-ICP-MS as the method of choice for dating, in comparison to other methods (Ion-probe, TIMS, ...)
- Data reduction in LA-ICP-MS: from measured counts per seconds to the final age of a sample, with hands on example.
- The challenge to date very young Zircons, with an example from Kos.

Ben Ellis:
- Ar-Ar dating techniques
-Ar-Ar dating of volcanic rocks
