About the video how does radioactive dating work:

Zheng , pp. Due to some published anomalies, I don't think we know that they have any clear relationship to the assumed dates. I believe that the above shows the 3 source mixing to be natural and likely. However, if the crust is enriched in lead or impoverished in uranium before the mixing, then the age of the isochron will be increased.

So, you can use the radioactive elements to measure the age of rocks and minerals. First, the earth sciences: explain it emits. Each element comes in different forms, called isotopes, most of which are stable and do not change. I believe that the same considerations apply to concordia and discordia, but am not as familiar with them. From the above sources, we see that another factor influencing radiometric dates is the proportion of the magma that comes from subducted oceanic plates and the proportion that comes from crustal rock.

Let us consider processes that could cause uranium and thorium to be incorporated into minerals with a high melting point. The impression I have is that geologists are continually looking for new methods, hoping to find something that will avoid problems with existing methods.

Haha! I can't stop laughing when her ass keeps sticking to him, literally a fake ass bitch.

It appears that at one or more stages in the crystallization process, a separation of the solid and liquid components of a magma frequently occurs. Further, Faure explains that uraninite UO sub2 is a component of igneous rocks Faure, p. But as we saw above, processes that take place within magma chambers involving crystallization could result in a different concentration of uranium and thorium at the top of a magma chamber than at the bottom. Then these concentrations would be reduced by a factor of say r' p at point p, and so the new concentrations would be P p r' p , D p r' p , and N p r' p at point p.

In fact, considering all of the processes going on in magma, it would seem that such mixing processes and pseudo-isochrons would be guaranteed to occur. Let N p be the concentration of some non-radiogenic not generated by radioactive decay isotope of D at point p. Any process that is concentrating one isotope of radium will probably concentrate the others as well and invalidate these dating methods, too. When an unstable Uranium U isotope decays, it turns into an isotope of the element Lead Pb.

This probability of decay is the decay constant. We all know that, so we should all see the inherent problems with radioactive dating. What is radioactive decay? By studying other planets, we are learning more about our own planet.
