RUNAWAY SUBDUCTION AS THE DRIVING
MECHANISM
FOR THE GENESIS FLOOD
Figure 2 Numerical
calculation of viscous slab sinking into viscous medium with temperature and
strain rate dependent rheology. Reference viscosity is 1020 Pa s at 1600 K and zero strain rate in the upper
400 km and increases linearly with depth between 400 and 700 km by a factor
of 50. Strain rate threshold for power law creep is 3 x 10-13 s-1. Slab initially
is 100 km wide and 400 km high. Snapshots are at (a) 0.002, (b) 6.3, (c)13.6,
and (d) 20.1 x 106 yr. Stain
rates never become large enough for power law creep to occur.
