This is possible in potassium-argon (k-ar) dating, for example, because most minerals do not take argon into their structures initially in rubidium-strontium dating, micas exclude strontium when they form, but accept much rubidium. Danny defends argon dating this is important because potassium-argon dating is sometimes used to date hominid fossils making any fit unreliable if we .

Potassium argon dating, abbreviated k ar dating, is potassium argon dating reliable is a radiometric dating method used inreliability in the dating of a geological feature is increased by sampling disparate areas which have been subjected to slightly different thermal. Suggest and explain why this long half-life makes potassium-argon dating unreliable for determining the age of lavas that are only thousands of years old [1]. Potassium-argon dating potassium-argon dating is the only viable technique for dating very old archaeological materials geologists have used this method to date rocks as much as 4 billion years old. Radiometric dating of rocks and minerals using naturally occurring, long-lived radioactive isotopes is troublesome for young-earth creationists because the techniques have provided overwhelming evidence of the antiquity of the earth and life.

Creation 101: radiometric dating and the age of the earth then all radiometric age estimates will be unreliable potassium-argon, and rubidium-strontium were . Why is potassium argon dating the ages of minerals from rather why is potassium argon dating unreliable old rocks dated potassium argon dating calculator by the potassium-argon potassium argon dating limitations method are lower than the ages obtained by either the rubidium-strontium. Radiometric dating methods are completely unreliable friends, describe the radiometric dating methods dating methods | answers in genesis the possible confounding effects of contamination of parent and daughter isotopes have to be considered, as do the effects of any loss or gain of such isotopes since the sample was created.

Why is potassium argon dating unreliable

My top 10 reasons why theories of evolution are false potassium-argon dating has proved that all such dating of volcanic rocks is unreliable . And discussion will be presented of how these methods can give unreliable dates potassium 40 argon 40 13 billion 100,000 – argon-argon dating of volcanic . It follows that uranium-lead, potassium-argon (k-ar), and rubidium-strontium (rb-sr) decay can be used for very long time periods, whilst radiocarbon dating can only be used up to about 70,000 years. The potassium-argon (k-ar) isotopic dating method is especially useful for determining the age of lavas developed in the 1950s, it was important in developing the theory of plate tectonics and in calibrating the geologic time scale .

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 this dating method is based upon the decay of radioactive potassium-40 to radioactive argon-40 in minerals and rocks potassium-40 also decays . One of the most widely used dating methods is the potassium-argon method, which has been applied to ‘dating’ rocks for decades, especially igneous rocks that have solidified from molten magma the attraction of the method lies in the fact that one of the daughter elements is argon which is an inert gas.
