Radiometric dating sedimentary rock
The right figure is an enlargement of the block with Ryan and Sean (left to right). Chadwick brought this block to my attention in 1978.—was lifted, transported from right to left, and deposited on layers which, at the time, were soft mud. (See the deformed layers below and above the block.) Professor Chadwick correctly identified the lifting force: a very dense, rapidly-flowing, sand/mud/water slurry, which plucked the block off the lower quartzite layer upstream (far to the right of these pictures).Part of that “pink” quartzite layer is seen in the first picture (lower right).Below is the online edition of In the Beginning: Compelling Evidence for Creation and the Flood, by Dr. [See pages 111–149.] Visualize a deck of cards sliding across a table. That card, in turn, applies a decelerating force on the second card from the bottom. [ The Fountains of the Great Deep Liquefaction During the Compression Event ] While liquefaction operated during the flood phase, it acted massively once during the compression event, at the end of the continental-drift phase.Sediments, forced into a denser packing arrangement, released water.Sedimentary particles were crushed or broken, so their fragments filled the spaces between particles, releasing even more water.In the Grand Canyon, the Cambrian-Precambrian interface is an almost flat, horizontal surface exposed for 66 miles above the Colorado River.Layers above the Cambrian-Precambrian interface are generally horizontal, but layers below are tipped at large angles, and their tipped edges are beveled off horizontally.
Therefore, this sand was probably wet when the layers tipped.
The freed water, then forced up through the sediments, caused massive liquefaction.
As the sedimentary layers decelerated and compressed, they became more and more fluid.
Notice that the top (nearly horizontal) layers obviously slid over and beveled the tops of the tipped layers below.
Something, such as water was needed to lubricate the sliding, otherwise the horizontal layers would be wrinkled or crushed.

Therefore, evolutionists interpret the Precambrian as about 90% of all geologic time—a vast period, they believe, before life evolved.
