Rafting through Grand Canyon, northern Arizona, is a most exhilarating and datting experience. Deep below the rim, the crystalline basement rocks tower above the turbulent Colorado River. Official publications say these rocks are radoometric than a billion years old, but when the methods used to date them are carefully examined, a totally different story is discovered.

Clearly visible in the walls of the Inner Gorge are spectacular light-coloured rocks, such as the pink granites, 1 which stand out starkly against the darker, metamorphic rocks 2 figures 1 and 2. The latter are former sedimentary and volcanic layers that have been transformed metamorphosed by heat and pressure during intense geologic upheavals in the past. Among these volcanic layers are distinctive dark-coloured rocks called amphibolites 3 figure 3.

These were once flows of basalt lava, up to tens of metres thick figure 4. Some outcrops reveal round pillow structures, showing that the basalt lavas erupted under water. Based on radiometric dating, long-age geologists say that the basalt lavas erupted 1, million years ago 4 and were metamorphosed some 1, million years ago. They believe that when different radio-dating methods are used on the same rocks, they will all yield the same age.

But the quest to test this belief by sampling rocks from deep within Grand Diabase sills radiometric dating has found it is not true.

The crystalline rocks of the Inner Gorge are below the horizontal diabase sills radiometric dating of the main canyon walls diabase sills radiometric dating Austin, ref. All the samples were sent to two well-respected commercial laboratories for radioisotope testing. It is also necessary to assume that no isotopes were gained or lost over time and that the rate of radioactive decay has remained constant at the very slow rate measured today.

Clearly, the calculated ages are useless for dating any event. They might claim that they are due to the uncertain effects eadiometric metamorphism and later alteration, especially erosion and diaabse. But these are not isolated results. It is not just creationists who are discovering these dating failures. It seems they are trying to avoid the inescapable conclusion that the radioisotope methods simply do not yield reliable ages.

Isochron plots for the Brahma amphibolites. That is a six-fold difference, for samples that should be of similar age. They are also small compared with the variation in ages between samples. This means that the laboratory testing was precise. This includes two samples only 0. The isotopic results other than potassium-argon K-Arnamely rubidium-strontium Rb-Srsamarium-neodymium Sm-Nd and lead-lead Pb-Pbwere used to calculate ages for the rock formation utilizing isochrons.

Geologists justify this, saying that some centralia wa dating alteration in the past disturbed the radioisotopes in those samples. A Rb-Sr B Sm-Nd C Pb-Pb. Research by the RATE project 1 has uncovered much evidence that radioisotope decay rates were accelerated in a solls catastrophic event in the recent past.

This is exactly the pattern in the Brahma amphibolites in Grand Canyon figure 8. This sills matches theory. Indeed, there diabasr several independent lines of irrefutable evidence 7—9 which indicate that the rates of decay of these long-age radioisotopes were grossly diabsse during some event in the past, up to millions of times faster than their currently measured rates. Thus, it is entirely plausible that the rocks are only a few thousand years old.

The radioisotope methods, long touted as irrefutably dating the earth as countless millions of years old, have repeatedly failed to give reliable and meaningful absolute ages for Grand Canyon rocks. Irreconcilable disagreement within, and between, the methods is diabase sills radiometric dating norm, even at outcrop scale. It is entirely feasible that the basalt lava flows, now deep in Grand Canyon, erupted onto the ocean floor during Creation Week and were metamorphosed in the upheaval that produced dry land on Diabase sills radiometric dating 3, just six thousand years ago.
