Does radiometric dating produce exact results

This gives us the impression that all but a small percentage of the dates computed by radiometric methods agree with the assumed ages of the rocks in which they are found, and that all of these various methods almost always give ages that agree with each other to within a few percentage points. After the material was quenched, the researchers measured up to 0. The percentage of published dates that are considered as anomalous has little bearing on the question. The results of the same lab test may not be accurate for what is it being tested for. It had been noted that some minerals which yield such dates as beryl, cordierite, etc.

However, there are some factors that must be accounted for. For example, sometimes it is possible for a small amount of new "parent" isotopes to be incorporated into the object, skewing the ratio. This is understood and can be corrected for. Carbon is the most commonly used isotope for dating organic material plants, animals. Plants and animals continually take in carbon during their lifespan. When they die, they no longer acquire carbon and so we can measure the decay of the isotope to determine when the plant or animal died.

Because carbon decays relatively rapidly compared to other isotopes, it can only be used to date things that are less than 60, years old. Anything older would have so little carbon left that you couldn't accurately measure it. However, the rapid decay allows precise dating - accuracy within just a couple decades. When dating older objects, namely rocks, it is necessary to use other isotopes that take a much longer time to decay.

The most common isotopes used are uranium and uranium there are multiple isotopes of uranium. The uranium isotopes eventually convert into lead isotopes. In does radiometric dating produce exact results words, we can predict the age of a rock within two million years out of two-and-a-half billion years.


That's pretty good. Do you believe radiometric dating is an accurate way to date the earth? Why or why not?

Could you also please explain further what radiometric dating is and the process to use it? Answer 1: Yes!! Answer 2: Yes, radiometric dating is a very accurate way to date the Earth.

This pretty much eliminates any significant laboratory biases or any major analytical mistakes. The second thing is that some of the results have been repeated using the same technique, which is another check against analytical errors. The third is that all three meteorites were dated by more than one method — two methods each for Allende and Guarena, and four methods for St Severin.

Does radiometric dating produce exact results is extremely powerful verification of the validity of both the theory and practice of radiometric dating. In the case of St Severin, for example, we have 4 different natural clocks actually 5, for the Pb-Pb method involves 2 classic for mature women radioactive uranium isotopeseach running at a different rate and each using elements that respond to chemical and physical conditions in much different ways.

And yet, they all give the same result to within a few percent. Is this a remarkable coincidence? Scientists have concluded that it is not; it is instead a consequence of does radiometric dating produce exact results fact that radiometric dating actually works and works quite well.

Creationists who wants to dispute the conclusion that primitive meteorites, and therefore the solar system, are about 4. One of the most exciting and important scientific findings in decades was the discovery that a large asteroid, about 10 kilometers diameter, struck the earth at the end of the Cretaceous Period.

Does radiometric dating produce exact results?

The collision threw many tons of debris into the atmosphere and possibly led to the extinction of the dinosaurs and many other life forms. The fallout from this enormous impact, including shocked quartz and high concentrations of the element iridium, has been found in sedimentary rocks at more than locations worldwide at the precise stratigraphic location of the Cretaceous-Tertiary K-T boundary Alvarez and Asaro ; Alvarez We now know that the impact site is located on the Yucatan Peninsula.

Measuring the age of this impact event independently of the stratigraphic evidence is an obvious test for radiometric methods, and a number of scientists in laboratories around the world set to work. In addition to shocked quartz grains and high concentrations of iridium, the K-T impact produced tektites, which are small glass spherules that form from rock that is instantaneously melted by a large impact.

The K-T tektites were ejected into the atmosphere and deposited some distance away. Tektites are easily recognizable and form in no other way, so the discovery of a sedimentary bed the Beloc Formation in Haiti that contained tektites and that, from fossil evidence, coincided with the K-T boundary provided an obvious candidate for dating.

Scientists from the US Geological Survey were the first to obtain radiometric ages for the tektites and laboratories in Berkeley, Stanford, Canada, and France soon followed suit. The results from all of the laboratories were remarkably consistent with the measured ages ranging only from Similar tektites were also found in Mexico, and the Berkeley lab found that they were the same age as the Haiti tektites. The K-T boundary is recorded in numerous sedimentary beds around the world.

Numerous thin beds of volcanic ash occur within these coals just centimeters above the K-T boundary, and some of these ash beds contain minerals that can be dated radiometrically. Since both the ash beds and the tektites occur either at or very near the K-T boundary, as determined by diagnostic fossils, the tektites and the ash beds should be very nearly the same age, and they are Table 2.

There are several important things to note about these naturist mature women. First, the Cretaceous and Tertiary periods were defined by geologists in the early s.

The boundary between these periods the K-T boundary is marked by an abrupt change in fossils found in sedimentary rocks worldwide. Its exact location in the stratigraphic column at any locality has nothing to do does radiometric dating produce exact results radiometric does radiometric dating produce exact results — it is located by careful study of the fossils and the rocks that contain them, and nothing more.

Furthermore, the dating was done in 6 different laboratories and the materials were collected from 5 different locations in the Western Hemisphere. And yet the results are the same within analytical error.

In the early afternoon of August 24, 79 CE, Mt Vesuvius erupted violently, sending hot ash flows speeding down its flanks. These flows buried and destroyed Pompeii and other nearby Roman cities. We know the exact day does radiometric dating produce exact results this eruption because Pliny the Younger carefully recorded the event.

They separated sanidine crystals from a sample of one of the ash flows. Incremental heating experiments on 12 samples of sanidine yielded 46 data points that resulted in an isochron age of 94 years. The actual age of the flow in was years.
