Age dating of the earth and its rocks

The Age of the Earth

But anyway, I think it is important really to know what patterns appear in the data to try to understand if there is a correlation and what could be causing it. He placed the man into a special garden that He had planted Genesis 2: So we have a number of mechanisms that can introduce errors in radiometric dates.

The rock cycle, as we now know, is driven by plate tectonics, with sedimentary material vanishing into subduction zones. This transformation may be accomplished in a number of different ways, including alpha decay emission of alpha particles and beta decay electron emission, positron emission, or electron capture.

This would probably have a larger effect lower down, where the pressure of argon would be higher.

Radiometric dating

And such flows often have a large internal scatter of dates, but these dates are not considered as anomalies because of the unrestricted biostratigraphic limit. Let me clarify the problem with excess argon. Geologists often say that the percentage of anomalies is low. Argon, the daughter substance, makes up about one percent of the atmosphere, which is therefore a possible source of contamination.

It is true that this can be accounted for by the fact that argon in the air has Ar36 and Ar40, whereas only Ar40 is produced by K-Ar decay. But for rocks deep in the earth, the mixture of argon in their environment is probably much higher in Ar40, since only Ar40 is produced by radioactive decay.

Luminescence dating Luminescence dating methods are not radiometric dating methods in that they do not rely on abundances of isotopes to calculate age. This involves inspection of a polished slice of a material to determine the density of "track" markings left in it by the spontaneous fission of uranium impurities.

If such [excessive] ages as mentioned above are obtained for pillow lavas, how are those from deep-sea drilling out in the Atlantic where sea-floor spreading is supposed to be occurring? Now we have to be careful about lava flows -- which geologic period do they belong to? It follows that radioactive decay rates were much higher in the past.

And the earth brought forth vegetation, plants yielding seed after their kind, and trees bearing fruit, with seed in them, after their kind; and God saw that it was good. The claim that the methods produce bad results essentially at random does not explain why these "bad results" are so consistently in line with mainstream science.

They also pointed out that for the anomalies to be accounted for by excess argon, unreasonably high partial pressures of Ar during crystallization would have to be required. The implication is that this organic material was either contaminated by new C, or it was buried much more recently and OE dating methods are suspect.

Vardiman et al claim that this would result in unreliable radioisotopic dating. For example, a change in the strength of weak interactions which govern beta decay would have different effects on the binding energy, and therefore the gravitational attraction, of different elements.

Convective mantle and radioactivity InThomson had been made Lord Kelvin in appreciation of his many scientific accomplishments. Boltwood focused on the end products of decay series. And we should resist the temptation to blame them for their resistance. The fact that the only "valid" K-Ar isochrons are those for which the concentration of non-radiogenic argon Ar36 is constant, seems very unusual.

It is claimed that we can know if a rock has added argon by its spectrum when heated; different temperatures yield different fractions of argon.Sep 27,  · Earth’s first life evolved in hell.

The earliest lifeforms emerged at least billion years ago, at a time when a near constant barrage of comets and asteroids were bombarding our still.

How Old is the Earth

Introduction. Today, the vast majority of pastors and teachers do not interpret the days of creation to be twenty-four hours long. Many accept the current secular view of the age of the earth, and rather than questioning the “sure” and “tested” results of “science” they conclude that a literal six day creation is a misinterpretation of Scripture.

Since the planet Earth doesn't have a birth certificate to record its formation, scientists have spent hundreds of years struggling to determine the age of the planet.

The age of the Earth is ± billion years ( × 10 9 years ± 1%). This age may represent the age of the Earth's accretion, of core formation, or of the material from which the Earth formed. This dating is based on evidence from radiometric age-dating of meteorite material and is consistent with the radiometric ages of the oldest-known.

How radiometric dating works in general: Radioactive elements decay gradually into other elements. The original element is called the parent, and the result of the decay process is called the daughter element. Most people accept the current old-earth (OE) age estimate of around billion years.

This age is obtained from radiometric dating and is assumed by evolutionists to provide a sufficiently long time-frame for Darwinian evolution.
