GEOINFORMATICS: HISTORY OF FORMATION, SUBJECT OF RESEARCH, METHOD, PROBLEMS (TODAY’S POINT OF VIEW). PART XXX

Kulinkovich A.E., Yakymchuk M.A.

This is the thirtieth paper in a series of publications that are dedicated to fundamental problems of geoinformatics, namely the subject of scientific research, main aims of the new science and methods of solving its specific tasks. In the present article the authors are discussing results of studying the history of our Milky Way Galaxy on the basis of deciphering the “stone chronicle” of the Earth’s crust. It is shown that the Galaxy has twice transformed into a spiral barred (SB) type: at first in the Archean and early Proterozoic period and then in the late Proterozoic over. Each time the direction of the galactic bars was controlled by the galactic magnetic field. An intersection galactic bar by the Solar system clearly reflects in the geological history: at that time planetary glaciations as well as formation of iron ore deposits took place.
