I The Moon

History of study.
The Moon as a celestial body.
Structure, chemical composition and mineralogy.
Lunar geology.
Data on the age of the Moon.

II Solar system

Beginning of the Solar system.
Extrosolar planetary systems.
Possible scenarios of accumulation of planets.

IV The model of formation of the Earth-Moon system via fragmentation of the initial gas-dust concentration

Enrichment of the Moon in refractory elements and depletion in volatiles.
Volatility of iron.
Evaporation of particles during contraction of the initial cloud is a crucial factor for both: dynamic of its fragmentation and depletion of the Moon in iron.
Geochemical consequences following from the model and how they are reconciled with the observations.

V Isotope constraints for evolution of the gas-dust cloud initial for Earth and Moon and again of their formation

Stable isotopes
