Geochemical methods in geology 1300-OMGGW-GEP
Concise review of the knowledge on general. Isotope and organic geochemistry, especially with indications on its use as a tool to solution of the geological problems (substance origin, geochronology, genesis of the organic fossil fuels etc.). The following problems are presented:
-basic terms (nuclide, isotope, isobare, isotone), classification of the isotopes, mass defect etc.
-physical and chemical processes of stable isotope fractionation, kinetic effect, isotope exchange
-methods of measurement of the isotope ratios, expression of the isotope composition, definition of the delta value, isotope standards
-preparation of the samples to the isotope measurements
-differentiation of the isotope composition of oxygen and hydrogen in hydrosphere and lithosphere
-isotope composition of carbon in various geological environments and in biosphere
-isotope composition of sulfur in nature
-mechanism of decay of the radioactive isotopes and principles of geochronology
-energetic effects of the nuclear reactions
-potassium-argon method
-geochronological methods with use of uranium and lead isotopes
-radiocarbon method
-composition, activity scheme and geological role of biosphere
-origin of the fossil fuels (coals, oil and natural gas).
