A child mummy is found high in the Andes and the archaeologist says the child lived more than 2,000 years ago.
Most sedimentary rocks are thought to lose Argon because the crystal structure leaks Argon.
They do not believe that there is any alternative way to look at history. There is such a strong consensus of opinion on K-Ar dating and other similar topics that deal with the history of the Earth that alternative viewpoints are probably viewed as being counterproductive.
So when the data does not come out right, it is only natural that they assume that there is something wrong with the dates that do not fit the long age viewpoint. So, many people try to say something like: But this is not true either, the weight of evidence does not prove anything. Before we start, lets look at the specific K-Ar dating assumptions.
As Paul Giem notes: Thus one could pick the dates that fit one's expectations and create a very impressive list of dates with close agreement without there being more than a general correlation of most dates with one's expectations. Very intelligent people believe in the long history of the earth and they have good data to support them. However, I look at that same data and I come to very different conclusions. There is such a thing as multiple interpretation to the data base. The Assumptions used in K-Ar Dating On this web page I want to discuss a possible scenario that would allow K-Ar dates to indicate a short age chronology.
They think of the long age scenario of evolution as being fact. Such a discussion might never be allowed in normal scientific circles because of the assumptions they choose to believe as being true.
However, when they turn around and say that the data supports the evolutionary viewpoint and not the Creationary viewpoint. The rate of decay half-lifeand the branching ratio, of K have not changed.
The material in question lost all its argon at an identifiable time, the reset time.The seventh assumption is one that scientists are doing their best to fulfill.We should also be able to safely make this assumption. When the concentrations of the various K isotopes are measured, the results are always the same. There are some cases where K has been gained or lost; However, the mineral itself has been noticeably altered.Potassium–argon dating, abbreviated K–Ar dating, is a radiometric dating method used in geochronology and archaeology. Chronological Methods 9 - Potassium-Argon Dating The technique works well for almost any igneous or volcanic rock, provided that the rock.Potassium-argon dating, method of determining the time of origin of rocks by measuring the ratio of radioactive argon to radioactive potassium in the rock.
