Mt etna basalt carbon dating
Yet the column and its assumptions are used along with index fossils to assign dates to sedimentary rock layers and which in turn is used to date any fossil in that rock layer.
In geology, the buzzword is “The present is the key to the past” – but today – no 100 mile cavern systems are being formed, vitually no fossils are being formed, and no new strata covering entire continents are being laid down. Unfortunately, uniformitarianism has gripped geology academia and no other viewpoints are allowed.
Helens and Southwest Pacific tsunamis produced large deposits of multi-layered strata in a matter of hours or days… Yes, we all have been inundated with teaching that rocks are dated in the millions and billions of years, but are they really? Do they really NEED to be millions or billions of years old?
Actually the assignment of a certain number of millions of years to a rock formation does not derive from the strata itself.
It is a different story when the same rubidium-strontium method is used to date lava from volcanoes on the north rim of the Grand Canyon.
We know these volcanoes are some of the youngest rocks in the canyon, because they spilled lava into the canyon after it had been eroded.
These dating methods rely on a series of assumptions about the amounts of the parent-daughter elements, and a constant rate of decay. It has been accepted that a rock is formed when it first cools down from a molten or semi-molten state, which may include a variety of elements, including radioactive ones. For the last 100 years we have been able to measure the decay rate, and during this time it has been very steady, very consistent.This is despite the fact that it causes more problems for interpreting rock strata than it solves.And today we know through lab experiments and natural disasters (such as the eruption of Mt. Helens) that major layering of rock strata can happen catastrophically in a short period of time.Only recently, Creation magazine reported that ages up to 3.5 million years were obtained for lava flows that erupted in New Zealand from 1949 to 1975.2 One sobering example comes from the Grand Canyon in Arizona (see diagram, left).
The Cardenas Basalt in the bottom of the canyon is an igneous rock layer suitable for radioisotope technology.
In fact, the very concept of strata representing long ages does not come from the rock strata themselves.
