Chemical equilibrium. Acids and basis, buffers, (carbonate equilibrium, sea water as buffer, ion activity). Carbonate sediments (hydrolysis, carst phenomena, carbonate deposition, tuffa). Kinetics (chemical weathering, catalysis, complexation). Structural chemistry (bond types, isomorphism, polymorphism). Colloids, (organic, silica, Fe-Mn hydroxides, stability). Clay minerals and soil. Thermodynamic equilibria (phase rule, thermodynamic lows and functions). Eh-pH diagrams. Organic matter in sediments (diagenesis, epigenesis, maturation, genesis of oil and gas). Magma (Nernst coef. of distribution, REE, ionic potential, phase diagrams). Stabile isotopes, C,O,S,H, geothermometry. Radiogenic isotopes Rb/Sr, K/Ar, Ar/Ar, U-Th-Pb, Sm-Nd, 14C, geochronology. Historical geochemistry.
Learning outcomes:
Study of quantitative and isotope geochemistry requires basic knowledge of physics, chemistry, mineralogy and petrology. According to the past experience int he frame of Bologna process, the fundamental knowledge is elaborated, but students skills in solving geochemical problems by use of mathematical tools is not adequate.
In the progress of the course acquried skill is significantly improved by satisfactory time devoted to students practice. Laboratory exercise would be another way to improve understanding of complex subjects, and their application in the field of economic geology, petrology and geochemistry of environment.
Study program intensively uses Internet, great choice of text books and scientific journals.
