Polonium dating

Polonium dating path

Scorpion recap: Hard Knox

In order to find an age for the Earth, scientists and more recently creationists polonium dating looked to the field of geology to find answers. Both proponents of an old Earth and proponents of a young Earth have used characteristics of rocks to justify their theories. One utv online dating theory currently being used as evidence of a young Earth involves what are known as pleochroic halos. Pleochroic halos occur polonium dating certain types of igneous rock such as granite that contain minerals such as zircon and monazite, which can be inclusions within other minerals polonium dating as mica.

It is known that the crystal lattice of these minerals commonly contains traces of certain radioactive elements. These radioactive materials can leave radiation damage in the form of discoloration in the surrounding rock. This radiation damage or "halo" appears as a fuzzy spherical shaped discoloration in the mineral structure emanating from the location of the radioactive material as seen in figure 1.

Creationists polonium dating young earth proponents use a specific type of pleochroic halo, purported to be caused by the radioactive element polonium, to make the claim that the Earth could not be billions of years old, but must be much younger. It is important to note, however, that polonium halos do not give any specific age of the Earth and young Earth supporters are not attempting to use them as a dating method. Instead, polonium halos are seen as a way to discount scientists' polonium dating that the Earth has a geologic record which took billions of years to polonium dating.

In short, polonium halos are not natural clocks because they cannot be said to give any specific age, but creationists infer certain things about these halos that they say are evidence of a young Earth. The originator of the polonium halo theory as evidence for a young Earth is the physicist Robert V. He believes that he has found evidence in pleochroic halos of granites that indicate that the Earth cannot have been formed over millions or billions of years, but must have been created in a short amount of time, in keeping with the Genesis account of creation.

Gentry claims that halos such as the one in figure 2 were caused by traces of the element polonium in primordial granite i. He believes that because of polonium's remarkably short half-life, sometimes just microseconds long there is no way that these polonium dating could have formed through millions of years of cooling as geologists commonly claim, but instead must have formed nearly instantaneously, as by some supernatural power.

The basic point of Gentry's research is not to provide a specific date polonium dating the formation of the Earth, as polonium halos do not work well as a natural clock. Instead, it seems that Gentry's intentions are to throw the proverbial "monkey wrench" into the traditional scientific model for Earth's formation.

If the above assumptions are correct, Gentry asserts that the granites in which the proposed polonium halos were found cannot have been formed over millions or billions of years, but must have been formed in a relatively short amount of time because of the relatively short half-life of polonium. There is polonium dating no indication in Gentry's research of exactly when this proposed rapid formation of primordial granite took place, only that it happened quickly.

And so, if the formation of the primordial rocks of polonium dating Earth's crust did not take billions of years, then to Gentry this seems to make a young Earth more plausible. In short, Gentry's polonium halo research is not direct evidence of a young Earth, but indirect evidence. As will be shown below, however, even this australian online dating reviews evidence of a young Earth may not hold up to scrutiny "Fingerprints of Creation" Scientists such as Tom Baillieul and John Brawley have done research and published articles refuting Gentry's theory of polonium halos.

John Brawley is polonium dating amateur scientist who published an article about research he conducted which polonium dating that there are other radioactive materials polonium dating form halos which are indiscernible from polonium halos, making it impossible to tell whether or not the halos polonium dating Gentry studied are indeed formed by polonium dating Brawley Baillieul refutes Gentry's claims by examining his assumptions about the halos that he observed.

Baillieul claims that the assumption that the rock which these supposed polonium halos were found is primordial is not true. As Baillieul explains, Gentry is a physicist, not a geologist, and as a result he is not able to properly put the rocks being examined in their proper context. Gentry's samples were sent to him by colleagues from around the world, so he cannot be entirely sure how they fit into the geological time scale.

Baillieul asserts that the types of granite that Gentry uses are not actually primordial, and that some of them are not even granite as Gentry claims. Baillieul then challenges Gentry's assumption that the particular ring-shaped halos that he observed can be positively identified as the result of alpha particle bombardment. Gentry bases this assumption on past research done polonium dating a time when the structure of the atom was just being discovered.

Baillieul believes that that there are still some unanswered questions about being able to positively identify the type of radiation that caused a halo polonium dating on properties like the ring structure and color of the halos. He believes that for this reason the oddest dating sites that the observed halos are caused by alpha particle bombardment is at best speculative. Finally, Baillieul claims that even if it is assumed that the halos are cause by alpha radiation, that it seems more likely that the halos would have been caused by the decay of Radon Radon decays to Poloniumand is also part of the decay series of Uranium Since Uranium has half-life of approximately 4.

A recent book titled Thousands. Not Billions which touts a young Earth provides a more polonium dating creationist view on polonium halos. This research, which was conducted by the RATE project, claims to carry on Gentry's work on radiohalos, but in fact seems only to cause more confusion.
