Description

Prerequisites:

Chemical basis of geosciences

 

Brief description of the lecture:

The origin of the chemical elements, their formation in the Universe: nuclear fusion (from hydrogen to iron), slow and rapid neutron capture, proton capture (element heavier than iron), spallation nuclear reactions. Chemical processes during the Earth’s formation. The role of the reduction potential of the elements relative to that of iron in the primary differentiation of the elements. Main controlling factors in the secondary differentiation of the elements: melting point (lattice energy: the size and the charge of the ions) and the abundance of the elements. Continuous changes: weathering. Geochemical classifications of the elements. Geochemical properties of the main terrestrial reservoirs (exo- and endogeospheres) of the elements. Formation of the atmosphere and hydrosphere, their composition and the changes in their composition during the history of the Earth. Seismic waves. Types of meteorites. Characterization of the core, the mantle and the crust. The chemical bonds, crystal structure, the size of the ions, lattice energy, ion potential and their roles in the mobility of the elements. The formation of the geological organic matter and its accumulation in the sediments. The formation of fossil fuels.
