Potassium argon 40 dating
As Paul Giem notes: One has to wonder why these kinds of experiments were not originally done. Stanford University Press, p.

But geologists project a much smaller distance between the points at the time of the impact because of measured sea floor expansion. Introduction Is the prevalent view held by the majority of scientists the only plausible way of approaching the problems of time?
But the decay of potassium has multiple pathwaysand detailed information about each of these pathways is necessary if potassiun-argon decay is to be used as a clock. In addition, some rocks may have been reheated so that the clock was partially reset or fully reset at a later date. The data does not support long ages.
The calcium pathway is not often used for dating since there is such an potassium argon 40 dating of calcium in minerals, but there are some special cases where it is useful. Since the crustal basement in the Best free dating site in france area was known to have an age in the neighborhood of the older age, this gave some confirmation to the Chicxulub crater as the origin of the K-T boundary layer. If we know when a lava flow was made because it happened recently, and we then check to see how much Argon is in the rock; That measurement will tell us how well the Argon actually came out of the rock.
However there may be a new development in the field of nuclear reactions that could change this situation. How can these dates be made to agree with each other?
However, there is a problem with Ca What is meant by filtered data, is that they only present the data that agrees with evolutionary thinking. Later, when we start discussing the K-Ar dating technique from a Creationary perspective, we will see that this reseting of the clock is a major issue.
In effect, the accuracy of ideas is limited by the assumptions chosen by the researchers.
However, when the volcanic lava flow, goes underwater, into the sea; It shows progressively excess ages. Most scientists do not believe that the short chronology of the Bible has any validity at all and most would consider it counterproductive to pursue such a course of investigation. In the experiment, the Argon that was absorbed into the rock looked just like the normal radiogenic Argon that comes from K 40!
The potassium argon 40 dating of decay half-lifeand the branching ratio, of K have not changed. No argon has been lost since the time the rock was reset, or set to zero. Because of what is considered to be an impossibility, the modern forms are assumed to have been examples of intrusions. This simplified conceptual treatment does not give a fair picture of the detailed design and execution of age determinations for a wide variety of types of geological samples.
The fifth assumption is fairly safe. Some samples will not be fully reset, initially.
Some of these reactions occur under admittedly extremely mild conditions, However, it is another question to suppose that these newly discovered processes can occur or did occur in natural conditions, in the history of our world.
But in this case the nature of zircon was an advantage.
