3. Future of Universe

4. Presently known elementary particles of the universe Elementary particles Fermions (matter carriers) Bosons (force carriers) LeptonsQuarks Weak (bosons) Strong (gluons) Electro- magnetic (photon) Gravity (graviton) electron neutrino upW - bosoncolor 1 E 1 =h 1 * electrondownW + boson color 2 E 2 =h 2 muon neutrino charmZ o boson color 3 E 2 =h 2 muonstrange E 3 =h 3 tau neutrino top E n =h n taubottom * not yet discovered

5. Elements of matter

6. Cycle of processes in the Earth crust

7. Magmatic process

8. Relation between chemical elements and type of magmatic rocks

9. Ore deposits formation, for example

10. Crystalline solids 7 elemental cells

11. A description of the inner structure of crystals makes use of 7 crystallographic systems containing 32 elements of symmetry combined with 14 translation lattices. The combination of 32 classes of symmetry and 14 translation lattices makes 230 space groups. particular crystal must belong to one of the 230 space groups To distinguish between space groups there are used two different, international and the Schoenflies, notations. For example, the symbol of NaCl lattice in the international system is Fm3n while in the Schoenflies system is O5h.

12. Solid chemical compounds occurring in Nature are called minerals Presently we know about 4 000 minerals It is recommended to use names endorsed by the Committee on Names of Minerals and New Minerals of the International Mineralogical Association

13. Learn by heart names of 100 most important minerals Remember:
