Rdiometric dating - speed dating how to organise

For example in a 1969 article, volcanic rock from Mt.Rangitoto in New Zealand gave potassium-argon ages of hundreds of thousands of years, but trees destroyed by the lava gave carbon-14 ages of hundreds of years.

In many cases these assumptions seem to be valid, and when they are not it is often obvious.CREATIONIST RESPONSES First are several suggestions for young earth creationists studying radiometric dating: (a) work within the scientific community and use caution when making scientific claims; (b) work toward a constructive alternative model, more than just attacking existing models; (c) address the big picture, more than scattered discrete pieces of data; (d) don’t expect quick “silver bullet” proofs for the Bible; and (e) origins activities are one-time events, so don’t expect any origins research to fit a purely naturalistic scientific model.Using the current understanding of radiometric dating, it is difficult to fit the data into a one-year flood a few thousand years ago; however, creationists have given a number of responses that are here divided into eight categories: (1) The radiometric age data is bad.(2) Geochemistry suggests alternate time interpretations for the parent-daughter ratios.– (a) Radiometric ages for some minerals may not give the time of emplacement of the volcanic or granitic rock because the minerals were formed earlier and the emplaced magma was not hot enough to melt them.The exact age is easily determined with a simple equation.

Of the many radioactive parent-daughter pairs of atoms, about half a dozen are used for age dating. (a) Carbon-14 methods can date organic material such as bones, wood, and shells directly.

(a) The strong force that governs nuclear decay rates is several orders of magnitude greater than the electromagnetic force that governs atomic interactions at even the highest temperatures and pressures found on earth.

Only at the high temperatures in the interior of stars would the decay rates be expected to change significantly.

For example, loss or gain of parent or daughter atoms might be expected if the sample shows signs of mechanical breakdown, chemical weathering, or metamorphic high pressures and temperatures.

Following are three of the many reasons that scientists put confidence in radiometric dates: (1) Decay rates appear to be constant.

Seventh-day Adventists show their great interest in time by having it as part of their name, referring to a recent seven-day creation in the past and a soon-coming advent of Christ in the future.
