RADIOMETRIC DATING CLOCKS

Thus, rubidium and strontium in minerals tend to be inversely correlated; minerals high in rubidium are generally low in strontium and vice versa. The advocates of “scientific” creationism frequently point to apparent inconsistencies in radiometric dating results as evidence invalidating the techniques. These data cannot be used to calculate the age of the lava flows and no knowledgeable scientist would attempt to do so. Rybka (110) claims that experimental evidence suggests that decay rates have changed over time: Two cases where it appears that the half life is increasing with time are as follows. 3 percent, respectively, of the total iron. Thus, the Earth and the atmosphere now contain about equal amounts of 40Ar, and the total could be generated if the Earth contained only 170 ppm potassium and released half of its 40Ar to the atmosphere.

Also, if either the initial isotopic composition of strontium is not uniform or the samples analyzed are not cogenetic, then the data will not fall on a straight line. At any time after the episodic lead loss (say, 1 radiometric dating clocks. Neutron reaction corrections in the U-Th-Pb series reduce “ages” of billions of years to a few thousand years because most of the Pb can be attributed to neutron reactions rather than to radioactive decay. The straight lines, which seem to make radiometric dating meaningful, are easily assumed to be the result of simple mixing. Where Woodmorappe obtained his 140-million-year “expected” age is anyone’s guess because it does not appear in the report he cites. A few examples will illustrate that the comments by Slusher (117) and other creation “scientists” are based on ignorance of the methods and are unfounded.

It commonly substitutes for calcium in calcium minerals, such as the plagioclase feldspars. If the requirements of the method have been violated, the data clearly show it. However, to read any clock accurately we must know where the clock was set at the beginning.free no registration no sign up camsexsxxx.
. He presents an equation for making these corrections: based on the assumption that the neutron-capture cross sections 206Pb and 207Pb are equal, an assumption that Cook (28) calls “reasonable. .Courtship dating lyrics song meanings.

Radiometric dating was first applied by Bertram Boltwood who postulated that older uranium bearing minerals should contain a higher proportion of lead. Both uranium-238 and uranium-235 decay to produce lead-206 and lead-207 respectively.
http://www.bible.ca/tracks/dating-radiometric.htm

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. Assuming we start out with pure parent, as time passes, more and more daughter will be produced.
