Radiometric dating corals

It rests upon an extinct volcano, as expected, and the volcano rises about two miles above the ocean floor. Examination of the material from the bore holes reveals that this is a normal reef that formed from the cementing together of corals and lime-secreting algae.

(This algae is different from the kind that lives within the corals.) In addition, three unconformities (discontinuities in the growth of the reef) were located at depths of 300, 1000, and 2780 feet.

All we need to do is divide the height of the reef by the rate at which it grew.

This calculation is rather like finding how long it would take to travel a certain distance.

Admittedly, one may question whether the growth rate wasn't perhaps faster for this particular reef, but there are limits to how fast corals can grow.

This page, assembled by Craig Rusbult, is an "overflow" from a collection of pages with Examples of Old-Earth Evidence. Phillips Viewed from the air, Pacific coral reefs generally appear as circular islands called atolls.

This reef was thoroughly investigated by deep core drillings in preparation for its use as a test-site for a hydrogen bomb explosion.

This atoll is roughly circular with all the standard characteristics of a growing reef.

The most reasonable explanation for coral growth begins with a volcano.

Volcanoes can build themselves thousands of feet upward from the ocean floor, and some of them will grow tall enough to break through the surface of the water.
