The top of the "basaltic" layer may lie at 5 to 9 km below the surface in places and positions predictable geologically and radiochemically. A folded metamorphic complex (as old as 3.55 b.y.) is believed to exist at 3 to 4 km depth, underlain by ancient siallitic horizons which grade into the "basalt." The mean geothermal gradient in the Krivoy Rog Basin is 103 to 116 m/1°C, increasing slightly with depth. Not more than 100 to 120°C may be expected at depths of 10-12 km. — IGR Staff. |
