The energy locked in the nucleus is enormous, but cannot be released easily.
The phenomenon we know as heat is simply the jiggling around of atoms and their components, so in principle a high enough temperature could cause the components of the core to break out.
Zincon has a very high closure temperature, is very chemically inert, and is resistant to mechanical weathering.
For these reasons, if a rock strata contains zircon, running a uranium-lead test on a zircon sample will produce a radiometric dating result that is less dependent on the initial quantity problem.
A complex set of rules describes the details of particle decays: historically, the finding of which as been a major objective of particle physics.
For example, in uranium-lead dating, they use rocks containing zircon (Zr Si O Zircon and baddeleyite incorporate uranium atoms into their crystalline structure as substitutes for zirconium, but strongly reject lead.Another assumption is that the rate of decay is constant over long periods of time, which is particularly implausible as energy levels changed enormously over time.There is no reason to expect that the rate of decay of a radioactive material is largely constant, As early as of 1673, John Ray, an English naturalist, reckoned with alternative that "im the primitive times and soon after the Creation the earth suffered far more concussions and mutations in its superficial part than afterward". Atoms consist of a heavy central core called the nucleus surrounded by clouds of lightweight particles (electrons), called electron shells.However, the nucleus has a strong positive charge and the electron shells have a strong negative charge. Those that can decay are mesons and baryons, which include protons and neutrons; although decays can involve other particles such as photons, electrons, positrons, and neutrinos.Any incoming negative charge would be deflected by the electron shell and any positive charge that penetrated the electron shells would be deflected by the positive charge of the nucleus itself. "Decay" simply refers to a meson or baryon becoming another type of particle, as the number of a certain type of particle goes down or decays as they are converted.Radiometric dating is mostly used to determine the age of rocks, though a particular form of radiometric dating—called Radiocarbon dating—can date wood, cloth, skeletons, and other organic material.
