Mineral found in granite radiometric dating

geoscientists estimate the rock formation is 1.5 billion years old.

But creation scientists found the zircons retained surprisingly high amounts of the helium that the uranium-to-lead decay would have produced.

They also measured how fast argon leaks from the feldspar at various depths in the borehole.

Using those data, I show that even assuming that the deepest sample did not get hotter than its present temperature, it would have lost nearly all of its argon in a million years..

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.

Now, argon from the same site has become a second noble-gas witness confirming the biblical youth of the world. Well, this site provides over 30 years of information. Would you support our efforts to keep this information coming for 30 more years?

To my surprise, I found that this paper had completely ignored the heat that the nearby volcano (Figure 2) would have applied to the formation during the alleged one million years since its eruption.

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.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.They modelled past temperatures in the formation using argon data in the borehole as a constraint.That means that RATE’s assumption of constant temperatures was actually quite generous to uniformitarians. Feldspar from Colorado, of the same type (microcline) as in the RATE borehole. Feldspar, a common mineral in the granitic rock (Figure 3), contains a lot of potassium, about 0.01% of which is the radioactive isotope potassium-40.Impurities in this variety (amazonite) colour the normally-white crystals blue-green. Today it decays very slowly into the stable isotope argon-40.Scientists use formulas an calculations to discover new things all the time, but they have the support of their secular peers and the public.
