Re: K-Ar Dates Not Reliable At All
there are lots of diferent dating methods that do not work on the priciple of atom decay and they still point to the same timescale thus supporting the dating methods you do not like
to name a few
Stratigraphy
Seriation
faunal dating
amino acid racimization
Cation-ratio dating
Thermoluminescence dating
and i guess they are also all wrong cause they support other dating methods like radiocarbon dating and that is a no no cause the erth cannot be older than 6000 years that would go against the bible and the word of your god.

Re: K-Ar Dates Not Reliable At All
so what is the assumption in Thermoluminescence dating or Optically stimulated luminescence (OSL)

Re: K-Ar Dates Not Reliable At All
il give you a bit of help so you will know how the dating methods work so you wont google your time away.
Thermoluminescence dating is very useful for determining the age of pottery. Electrons from quartz and other minerals in the pottery clay are bumped out of their normal positions (ground state) when the clay is exposed to radiation. This radiation may come from radioactive substances such as uranium,
present in the clay or burial medium, or from cosmic radiation. When the ceramic is heated to a very high temperature (over 932F [500C]), these electrons fall back to the ground state, emitting light in the process and resetting the "clock" to zero. The longer the radiation exposure, the more electrons get bumped into an excited state. With more electrons in an excited state, more light is emitted upon heating. The process of displacing electrons begins again after the object cools. Scientists can determine how many years have passed since a ceramic was fired by heating it in the laboratory and measuring how much light is given off. Thermoluminescence dating has the advantage of covering the time interval between radiocarbon and potassium-argon dating, or 40,000—200,000 years. In addition, it can be used to date materials that cannot be dated with these other two methods.
from Just a moment...
and
Optically stimulated luminescence (OSL) has only been used since 1984. It is very similar to thermoluminescence dating, both of which are considered "clock setting" techniques. Minerals found in sediments are sensitive to light. Electrons found in the sediment grains leave the ground state when exposed to light, called recombination. To determine the age of sediment, scientists expose grains to a known amount of light and compare these grains with the unknown sediment. This technique can be used to determine the age of unheated sediments less than 500,000 years old. A disadvantage to this technique is that in order to get accurate results, the sediment to be tested cannot be exposed to light (which would reset the "clock"), making sampling difficult.
from the same site
these quotes give a detailed description of how the 2 dating methods work so tell me where lies the unproven assumption

Re: K-Ar Dates Not Reliable At All
i can anwser the tree ring dating one the problem lies that trees sometimes make rings more often than in one year though it is not known why some speculate it has to do whit humidity and temperature so as an exsact dating method it fails though as an aproximate dating method it is ok so if you get 3000 rings in a tree it could be that the tree is only 2500 years old it dosent give an exsact age but sets the ballpark

Re: K-Ar Dates Not Reliable At All
and i lerned something new today
and a bit offtopic i wish my trees made more rings in a year they make 2'5 cm rings witch makes the wood of porrer qualety though i do get more of it do to the fast growth( smreka, jelka )
and to the crationlibery guy you will haveto tare down the mountin of evidence we have from every angle and build your own mountin of evidence for a young Earth to make us believe it
