The 40Ar/39Ar laboratory

Evolutionists determined the age of this sedimentary layer from the ages of the layers of volcanic ash above and below it using potassium-argon dating. It was originally believed that all argon escapes from volcanic ash and lava at the time of eruption. Therefore, any argon gas found in the ash must have come from radioactive decay of potassium. The longer the time since the eruption, the more argon gas there would be trapped in the solid ash. The assumption that all the argon gas escapes at the time of eruption was shown to be false by measuring the amount of argon gas present in ash and lava from modern volcanic eruptions. So, evolutionists attempt to figure out how much argon was in the ash originally, and how much has been produced by radioactive decay since the eruption. The conventional K-Ar dating method depends on the assumption that the rocks contained no argon at the time of formation and that all the subsequent radiogenic argon i.

Potassium–argon dating, abbreviated K–Ar dating, is a radiometric dating method used in geochronology and archaeology. It is based on measurement of the product of the radioactive decay of an isotope of potassium (K) into argon (Ar). Potassium is a common element found in many materials, such as micas, clay minerals, tephra, and evaporites.

Geologic Column ,” we covered how the geologic column is made up from pure imagination, so what did the quote just tell us? They throw out an age they get if it doesn’t line up with their geologic column, or more simply put, they throw out a date they get if it doesn’t line up with how old they already think it is!

Let’s say an evolutionist gets radiometric dates of an object, and the lab will pull back all sorts of wild numbers, lets say ranging from. This is exactly how it’s done, and all of it comes down to the circular reasoning dating methods used for fossils dating rocks and rocks dating fossils. In , Nature April 18th, p. It had been dated many times with K-Ar, and almost every evolutionary scientist in the world agreed that the KBS tuff was million years old.

This was an important publication because this dated volcanic rock was going to be used as an ‘event horizon’, which means all other dates for all other findings in this area would then be cross-referenced to the KBS tuff. Remember earlier how I pointed out that they don’t really date things by radiometric dating, and how they actually use the geologic column?

Humans were not supposed to be in existance until 3 million years ago, according to the geologic column, and this human skull created a major conflict. We average laymans would expect scientists since they claim to be truly unbiased to reconsider how long mankind has been on the earth, and to question if their geologic column needs to be adjusted based on the evidence, but that is not what they did.

Before continuing to talk about what they did, we know two things for certain: Many evolutionary scientists know radiometric dating does not work properly. Evolutionists are dating objects based on the imaginary geologic column, not by any scientific method. After finding this skull that upset their geologic column, the evolutionists took ten more samples, despite the fact that it was already dated MANY times.

For more than three decades potassium-argon (K-Ar) and argon-argon (Ar-Ar) dating of rocks has been crucial in underpinning the billions of years for Earth history claimed by evolutionists. Critical to these dating methods is the assumption that there was no radiogenic argon (40 Ar *) in the rocks.

Departures from this assumption are quite common, particularly in areas of complex geological history, but such departures can provide useful information that is of value in elucidating thermal histories. A deficiency of 40 Ar in a sample of a known age can indicate a full or partial melt in the thermal history of the area. Reliability in the dating of a geological feature is increased by sampling disparate areas which have been subjected to slightly different thermal histories.

Ar—Ar dating is a similar technique which compares isotopic ratios from the same portion of the sample to avoid this problem. Applications[ edit ] Due to the long half-life , the technique is most applicable for dating minerals and rocks more than , years old. For shorter timescales, it is unlikely that enough 40 Ar will have had time to accumulate in order to be accurately measurable.

K—Ar dating was instrumental in the development of the geomagnetic polarity time scale. One archeological application has been in bracketing the age of archeological deposits at Olduvai Gorge by dating lava flows above and below the deposits. In the K—Ar method was used by the Mars Curiosity rover to date a rock on the Martian surface, the first time a rock has been dated from its mineral ingredients while situated on another planet.

Lies of Evolution: K

The Potassium Argon Reaction Ar 40 is used for several reasons. First of all, Argon is inert. It does not chemically react with other elements at all. So Argon does not attach itself to the rock or any minerals in the rock.

problems with radiocarbon dating During the last 30 years, a new method of determining C14/C12 ratios has been developed. It uses accelerator mass spectrometry to determine the amounts of C14 and C12 in a small sample which is vaporised in the test.

Hebeda Show more https: The M1 granulite-facies metamorphism has locally been followed by an M2 amphibolite-facies retrogradation to varying degrees. Three of the hornblendes olive-green and orange—brown come from granulites not showing any M2 retrogradation. They were produced as a stable phase during M1 and are concordant at approximately Ma. Of the other hornblendes Bluish-green , two come from completely M2 retrograded rocks and one from a post-M1 metadiorite. Two of them, one M2 hornblende and the metadiorite hornblende, are concordant with the M1 hornblendes, the third is somewhat older.

Taking also into account an earlier U-Pb zircon investigation and U-Pb zircon data reported from the Wami River granulite complex to the northeast, the M1 granulite-facies metamorphism is dated at approximately Ma and the termination of the M2 amphibolite-facies retrogradation at approximately Ma.

As discussed in Dalrymple (, p. ), 40 Ar/ 39 Ar has been developed as an alternative or supplement to K/Ar dating. 40 Ar/ 39 Ar has a number of advantages over K/Ar and circumvents any atmospheric argon contamination problems.

Go Back Argon-Argon Dating and the Chicxulub Impact In the early s there was an intense controversy about the association of the Chicxulub Crater of the Mexican Yucatan Peninsula with the extinction of the dinosaurs in the period about 65 million years ago. The Cretaceous-Tertiary boundary in the geological age scale was associated with an iridium-rich layer which suggested that the layer was caused by an impact with an extraterrestrial object. Because that time period, commonly referred to as the K-T boundary, was associated with the extinction of vast numbers of animals in the fossil record, much effort was devoted to dating it with potassium-argon and other methods of geochronology.

The time of 65 million years was associated with the K-T boundary from these studies. Other large impact craters such as the Manson crater in Iowa dated to 74 My were examined carefully as candidates for the cause of the extinction, but none were close to the critical time. Chicxulub was not so obvious as a candidate because much of the evidence for it was under the sea. More attention was directed to the Yucatan location after published work by Alan Hildebrand in demonstrated the chemical similarity of Chicxulub core samples with material found distributed in the K-T boundary layer.

The Radiometric Dating Game

The burial of these organisms also meant the burial of the carbon that they contained, leading to formation of our coal, oil and natural gas deposits. As the rate of C14 formation is independent from the levels of normal carbon, the drop in available C12 would not have reduced the rate of C14 production. Even if the rate of C14 formation had not increased after the Flood, there would have been a fundamental shift in the ratio towards a relatively higher radiocarbon content.

The amount of C14 present in the pre-flood environment is also limited by the relatively short time less than years which had elapsed between Creation and the Flood. Even if one is generous and allows for the current rate of C14 production to have ocurred throughout this period, the maximum amount of C14 in existence then is less than a fourth of the amount present today. The last years have seen this effect occur in reverse.

By the way, Ar-Ar dating and K-Ar dating are essentially the same method, so between the two of them we obtain a large fraction of the dates being used. Some information from an article by Robert H. Brown at the Geoscience Research Institute site confirms the preponderance of K-Ar dating.

Thus we do not know the numeric age of any given layer. The civilizations that deposited the trash had a culture and industrial capabilities that evolved through time. The oldest inhabitants used primitive stone tools, later inhabitants used cups made of ceramics, even later inhabitants eventually used tin cans and then changed to Aluminum cans, and then they developed a technology that used computers.

This shows that society has evolved over the years. Similar cultures must have existed in both areas and lived at the same time. Thus we can make correlations between the layers found at the different sites by reasoning that layers containing similar distinctive discarded items artifacts were deposited during the same time period.
