It was discovered the spiral galactic year, a periodical movement of the Solar System around the centre of Galaxy relatively the Galaxy spiral pattern (period is equal to 352 million years). This discovery permits to construct the causal model of alternation of magnetic superchrons of normal and reversed polarity, because the galactic magnetic field is ?frozen? into the spiral pattern of the Galaxy). The galactic magnetic field is a field of the dipole, so it is very heterogeneous. The spiral galactic year can be divided into eight galactic seasons (hyperchrones): 1) the magnetic nr-hyperchron 13 + 352?i +/- 22 million years ago; 2) the magnetic Nr-hyperchron 57 + 352?i +/- 22 million years ago; 3) the magnetic N- hyperchron 101 + 352?i +/- 22 million years ago; 4) the magnetic Nr- hyperchron 145 + 352?i +/- 22 million years ago; 5) the magnetic nr- hyperchron 189 + 352?i +/- 22 million years ago; 6) the magnetic nR hyperchron 233 + 352 i +/- 22 million years ago; 7) the magnetic R-hyperchron 277+352i+/-22 million years ago; 8) the magnetic nR-hyperchron 321 + 352i +/- 22 million years ago (i=0, 1, 2...). The symbol N means that N-chrons dominate, the symbol R means that R- chrons dominate. N- hyperchron is the N superchron. The Earth moves along magnetic lines, the polarity is normal and there are no change of magnetic poles; in the R-hyperchron (in the R-superchron) the Earth moves against the direction of magnetic lines, the magnetic polarity is reverse and there are no changes of the Earth magnetic poles.
