Radiometric dating of crystals inside rocks

That allows us to assume (for simplicity of calculation) that the rock temperature has been roughly constant over those past few thousand years.Then, using Harrison’s own data and equations, I calculate that the feldspar in the rock formation would have lost the observed amount of argon in only 5,100 years, give or take a few millennia according to my estimate of the experimental uncertainty in the data.Creationist geophysicist Dr John Baumgardner told me that “given the small value for the measured heat conductivity of granite, such a temperature scenario for this site is not defensible, since it violates the simple and well-known physics of heat diffusion.” The rock in the borehole is dry, which combined with its low heat conductivity means that its temperature cannot change rapidly. were correct in postulating a recent (and as yet completely unobserved) intrusion of lava very close to the borehole, the temperature could not have changed by more than 50 Celsius degrees (90 Fahrenheit degrees) over the past five millennia.for the site done by Los Alamos National Laboratory give much smaller changes.Comparing the two isotopes and assuming today’s rate of decay is the basis for the familiar ‘potassium-argon’ dating method, Harrison .found that in the deepest, hottest part of the borehole, over 20% of the nuclear-decay-generated argon has leaked out of the feldspar crystals.The critic wanted to increase the helium-leak age to over a billion years by having the formation be very much cooler in the past than it is at present. He depended heavily on a 1986 paper in the by geoscientists from three US universities.


Instead they assumed the temperature of the formation was incredibly low until relatively recently, an assumption that the helium critic welcomed because it supported his assertions.

Scientists use formulas an calculations to discover new things all the time, but they have the support of their secular peers and the public.

Even if they're wrong, the public will just swallow it whole.

were forced to assume the temperature was very low until relatively recently.

Then, they assumed that some unknown, unspecified source of heat rapidly raised the temperature in just twenty thousand years up to today’s high temperature.In contrast, the uniformitarian scenario of long ages would leave the rocks with almost no helium and little argon, contrary to the observations of both RATE and Harrison . every fact is to be confirmed by the testimony of two or three witnesses.” Helium from the RATE borehole has already testified to an earth that is thousands, not billions, of years old. The internet, and this site in particular, can be a powerful tool for reaching those who would never go to church.

    The issue most people have at that point is that there are just so many.
