would not be expected. 13 For volcanic rocks which cool from molten lavas, this would seem to be a reasonable assumption. However, the most violent explosions occurred on 19 February 1975, accompanied by what eye-witnesses described as atmospheric shock waves. A set of techniques similar to those already used for dating rocks on potassium-argon dating, read more dating us - Zoek dating us - Vind dating. Note, this Creation magazine article by Dr Snelling is based on his technical paper 21, which has far more detail about research methods and answers to possible criticisms than was possible in Creation magazine. This same failure is also known to occur in many other rocks, including both recent volcanics 18 and ancient crustal rocks. How can we trust the use of this same dating on rocks whose ages we dont know? Half-life of potassium-40 and because potassium is so common in many rocks. Read more How accurate are Carbon-14 and other radioactive dating As a Creationist, what about all the other radioisotope methods for dating the rock surrounding the fossils? However, the samples were described as probably young with very little argon in them so as to ensure extra care was taken during the analytical work. Because argon is a gas, it should escape to the atmosphere due to the intense heat of the lavas.

Turbulent avalanches of ash and blocks swept down Ngauruhoes sides at about 60 km (35 miles) per hour. It depends on the rate at which radioactive potassium decays into the gas argon.
