Radioactive decay[ edit ] Example of a radioactive decay chain from lead Pb to lead Pb. The final decay product, lead Pb , is stable and can no longer undergo spontaneous radioactive decay. All ordinary matter is made up of combinations of chemical elements , each with its own atomic number , indicating the number of protons in the atomic nucleus.

the radioactive dating of the earth’s rocks by geologists has supposedly proved that the earth is billions of years old. the radioactive dating method under heavy ‘fire’ The big surprise is that the attack has come from an evolutionary geologist and has been published in a secular scientific journal!

This is very possible, and even likely. It is only an assumption that integral or adjacent lead could only be an end-product. In addition, there is “common lead, “which has no radioactive parent lead This could easily be mixed into the sample and would seriously affect the dating of that sample. Faul, an authority in the field, recognized it also: When the earth’s crust was formed, the primordial lead was frozen into rocks that also contained uranium and thorium in various ratios to lead.

When a uranium sample is tested for dating purposes, it is assumed that the entire quantity of lead in it is “daughter-product lead” that is, the end-product of the decayed uranium. The specimen is not carefully and thoroughly checked for possible “common lead” content, because it is such a time-consuming task. Yet it is that very uranium-lead ratio which is used to date the sample!

The same problem applies to thorium samples. Part of the uranium and its daughter products could previously have leached out. This would drastically affect the dating of the sample.

## The Age of the Earth

Radioisotope dating shows the earth to be billions of years old. T38, 4: What We Really Know about Dating Methods When someone mentions scientific dating methods, the first thing to come to mind for most people is carbon dating. However, there are many methods that can be used to determine the age of the earth or other objects. The textbooks focus on relative dating, based on the layering of the rocks, and radiometric dating.

Relative ages are assigned to rocks based on the idea that rock layers lower in the strata were deposited before rock layers that are higher.

Radiometric dating, or radioactive dating as it is sometimes called, is a method used to date rocks and other objects based on the known decay rate of radioactive isotopes.

This age is obtained from radiometric dating and is assumed by evolutionists to provide a sufficiently long time-frame for Darwinian evolution. And OE Christians theistic evolutionists see no problem with this dating whilst still accepting biblical creation, see Radiometric Dating – A Christian Perspective. This is the crucial point: Some claim Genesis in particular, and the Bible in general looks mythical from this standpoint.

A full discussion of the topic must therefore include the current scientific challenge to the OE concept. This challenge is mainly headed by Creationism which teaches a young-earth YE theory.

All ordinary matter is made up of combinations of chemical elements , each with its own atomic number , indicating the number of protons in the atomic nucleus. Additionally, elements may exist in different isotopes , with each isotope of an element differing in the number of neutrons in the nucleus.

A particular isotope of a particular element is called a nuclide. Some nuclides are inherently unstable.

earth’s surface and formations. One method that is commonly used is radiometric dating. In reality these methods have many limitations. Most of these limitations have not been properly addressed. this is an absolute dating method.

This age is obtained from radiometric dating and is assumed by evolutionists to provide a sufficiently long time-frame for Darwinian evolution. And OE Christians theistic evolutionists see no problem with this dating whilst still accepting biblical creation, see Radiometric Dating – A Christian Perspective.

A full discussion of the topic must therefore include the current scientific challenge to the OE concept. This challenge is mainly headed by Creationism which teaches a young-earth YE theory. A young earth is considered to be typically just 6, years old since this fits the creation account and some dating deductions from Genesis. The crucial point here is: Accepted Dating Methods Here we outline some dating methods , both absolute and relative, that are widely accepted and used by the scientific community.

Absolute dating supplies a numerical date whilst relative dating places events in time-sequence; both are scientifically useful. Radiometric Dating This is based upon the spontaneous breakdown or decay of atomic nuclei. Radioactive parent P atoms decay to stable daughter D atoms e.

## Radiometric Dating: Problems with the Assumptions

Making Sense of the Patterns This three-part series will help you properly understand radiometric dating, the assumptions that lead to inaccurate dates, and the clues about what really happened in the past. Most people think that radioactive dating has proven the earth is billions of years old. Yet this view is based on a misunderstanding of how radiometric dating works.

Geochronology is the science of dating and determining the time sequence of events in the history of the Earth. This web page provides an overview of selected geochronology methods used by USGS scientists. New dating methods are invented all the time, however, most have practical limitations.

Dating techniques Photo by: Bastos Dating techniques are procedures used by scientists to determine the age of an object or a series of events. The two main types of dating methods are relative and absolute. Relative dating methods are used to determine only if one sample is older or younger than another. Absolute dating methods are used to determine an actual date in years for the age of an object. Relative dating Before the advent of absolute dating methods in the twentieth century, nearly all dating was relative.

The main relative dating method is stratigraphy pronounced stra-TI-gra-fee , which is the study of layers of rocks or the objects embedded within those layers.

## DATING METHODS SCIENCE

It cannot date fossils and rocks and can only date objects that are a few thousand years old, not millions of years old. Radiological dating gives rather extreme age variation, and its interpretation requires many assumptions. The truth is that new scientific discoveries and radiocarbon dating prove that evolution is a hoax. Radiocarbon dating can only date an object that is about 30, or so years old.

It has a half life or decay rate of 5, years, and after half lives, it becomes too small to measure. We can only use radiocarbon dating to date items several thousand years old.

Potassium Argon Method – What is it? This metal turns into gas Ar and then it is measured to determine the age of rocks. DON’T know how much gas Ar was in the rock originally unknown starting point!

It is the symbol for Potassium metal which decays to gas. It is the symbol for gas.
