(in Polish) Geochronologia-wdw 1300-WGCHP-GES

The subject presents modern techniques applied to the age determination based on measurements of isotope ratios in rocks and minerals. The course starts with presentation of some basic information on an atom composition. Radioactive decay and ways of dacay ( are presented. As a valuable method which is applied with the use of equipment present at the Faculty of Geology a chemical dating of monazite is described. Various methods of mass spectrometry applied to isotope ratio measurements are described – SIMS, TIMS and ICP-MS-LA (including a visit to geochronology and isotope geochemistry lab in the ING PAN in Cracow). Classic method of zircon dating based on U/Th-Pb decay is presented in details (including a visit to the ion microprobe -SHRIMP lab at the PIG-PIB). Examples of application of the method are analysed with the use of Isoplote program using various Concordia diagrams. A group of methods based on isochron geochronology are also presented. Applications of Rb-Sr, K-Ar, Re-Os, Sm-Nd, Lu-Hf methods are described. Ar-Ar as a new developed on a basis of the K-Ar method is also presented (also in practise in the ING PAN lab in Cracow).
Some examples of specific methods –thermochronology - fission tracks and (U+Th)/He, C14 method. Important role of isotopes as good tracers of important geological processes is also underlined. Presented theory is connected with practical exercises in different laboratories including optical microscopy lab, scanning microscopy and electron microprobe labs at the Faculty of Geology. Students have possibility to learn these techniques and apply to geochronology.
