The number of fission-tracks formed a mineral is dependent on the uranium concentration and age; the initial concentration of fission-tracks will certainly be zero.The second of Jeanson’s assumptions can often be tested.The problem is that radioactive decay generates a tremendous amount of energy, and accelerating the process to this extent would produce enough heat to boil the oceans and melt a significant portion of Earth’s crust.

Again, this argument depends on the distorted YEC definition of uniformitarianism, and ignores many factors. Jeanson began his discussion of radiometric dating by describing the The first assumption given by Jeanson is not always necessary.

These elements occur naturally in nearly all rocks, and they account for the radioactivity you could observe with a Geiger counter.

The radioactive decay process can be described simply as the transformation of an unstable radioactive atom (called the parent) to a new atom (called the daughter) that may differ in atomic number, atomic mass, or both.

What matters in this case is not that the rock or mineral being dated has no initial strontium, but that the magma was homogeneous in terms of its Sr. The mathematics behind this technique are straightforward, and rubidium-strontium dating has been used successfully many thousands of times, even though it violates the first of Dr. In other radiometric dating techniques, we can be certain that there was no daughter when the mineral formed, without making assumptions that may or may not be true. A fission-track is formed when a nucleus of U spontaneously undergoes fission, rather than undergoing the more common emission of an alpha particle.

The two newly-formed nuclei, both being positively-charged, are repelled from each other with tremendous energy, and create a trail of damage in the crystal.

Can we find in rocks a natural clock that has been operating since they formed?



Did she have an equal chance of getting ahead given her roll or the dice in life.... this kind of young Chinese girls can 'fall in love' with old Chinese guys too as long as the old guy can provide the girl what they want: security in a relationship, financial stability, some added values such as a new life style, new experiences or a passport etc that she can never get by her own etc...well, I completely understand those girls' choice because thats the easiest way to cure their deep insecurity and lack of self-confidence. so this is kind of significant 'stability' through traditional Chinese parents eyes compared to a guy who is from a country that the divorce rate is over 50%.… continue reading »
