Figure 7. Vertical section of the tectonic breaking of the crust, passing across Elbrus Volcano and oriented along the Caucasus strike. (1) Contour lines showing the extent of the tectonic breaking of the crust: the thick lines are drawn with the interval of 10 arb. units, the thin ones show intermediate values with intervals of 2 or 1 arbitrary units; (2) the region (zone) of the highly broken lower crust; (3) nearly horizontal weak zones (potential flow of primary magma into the volcanic chamber); (4) region of abnormally low field values in the top of the basaltic crust, interpreted as a potential parental magma source which had supplied magmatic material to fill up the volcanic chambers; (5) region of abnormally low values in the upper crust, identified as a volcanic chamber [Nechaev and Sobisevich, 2000].
