Abstract:

Petrochemical variations in composition of basalts along the axial part of the Kolbeinsey mid-ocean ridge were studied. It was found that principal mass of these basalts has tholeiitic composition. Alkalinity of these basalts increases near zones of transform transverse faults; it increases likewise toward Iceland, and especially in the direction of Jan Mayen Island.
