Analytical methods 2 (SS2)

This module provides practical and theoretical skills in advanced analytical methods important for geological materials. It is compulsory  for the focus area "Geomaterials and Processes".

It consists of a laboratory part for the hands-on learning of different advanced analytical techniques and a lecture part in "High resolution spectroscopy".

Content:

Advanced analytical techniques:

• Clay mineralogy, clay mineral separation & identification by X-ray diffraction
• Cathodoluminescence methods (hot and cold cathode)
• Fluid inclusions study on heating/freezing stage
• Reflected light microscopy and application to ore forming minerals and ore mineral parageneses

High-resolution spectroscopy:

• Tools for the characterization of type and site of atoms as well as their first sphere surroundings (UV-VIS and IR)
• Surface analysis methods (X-ray Photon Spectroscopy (XPS), Secondary Ion Mass Spectroscopy (SIMS), Auger Spectroscopy (AGS), LEED and RHEED)
• Analysis of local geometry, the chemical state and coordination spheres of atoms (X-ray Absorption Spectroscopy (XAS), Extended Absorption Fine Structure (EXAFS), and X-ray Absorption Near Edge Structure (XANES), introduction into synchrotron technology).
• Oxidation state of atoms, e.g. Fe2+/Fe3+ (Mössbauer Spectroscopy)
• Other high-resolution methods like Raman spectroscopy, STM, AFM, and TEM microscopy
