Slabs in the Face of Deep Time
The dominant principle in old earth geology is uniformitarianism, which essentially means that present processes are the key to the past. Secular geologists shun catastrophic processes for the most part, but it puts burrs under their saddles when they are forced to invoke them on occasion. Of course, the global Genesis Flood is rejected out of hand. Such biases make for erroneous geological studies; some things are unexplainable from deep time conjectures. Take cold slabs and subduction, for example.
You have probably heard of plate tectonics, where plates on the earth's surface move. Secular scientists are unable to determine how plate tectonics began. The most popular model among biblical creationists is catastrophic plate tectonics, which began with the Genesis Flood. Plates do not simply collide. Subduction happens when one plate is forced under another one. There are oceanic slabs of rock that are far too cold to be explained by secular geology, and the more they study these slabs, the worse things get for their worldview.

Since the 1990s, cross-section images of mantle tomography have shown visible slabs of oceanic lithosphere (which includes oceanic crust) descending hundreds of miles beneath ocean trenches into subduction zones. These descending plates have been imaged all the way down to the top of the earth’s outer core and are composed of cold, brittle, dense rock about 62 miles thick.
Researchers from the University of Colorado recently reported finding that some of the subducted slabs stagnate at depths of about 670 km (416 mi) to 1000 km (620 mi) and appear to travel horizontally.To read the rest, click on "Cold Slabs Indicate Recent Global Flood".
