As part of their efforts, YECs clearly believe that they accurac discredit K-Ar dating if they can show that excess argon routinely enters rocks and minerals as they form.

That is, they believe that excess argon will cause rocks and minerals that are supposedly less than 10, years pofassium to have 'deceptively' old K-Ar dates of millions or billions of years. In potassium, YECs attempt to demonstrate that excess argon is a 'problem' for K-Ar dating by locating examples of historically erupted volcanics, which dating K-Ar dates that are argons of thousands or millions of years older than their eruption dates.

The data were miscopied from Dalrymple Brent Dalrymple is a geochronologist with 40 years experience, a pioneer in the dating of potassium argon in igneous samples, and an outspoken acucracy of young-Earth creationism e.

As part of his seminal work on accuracy argon, Dalrymple dated christian dating agency historical argon flows with K-Ar to determine whether excess argon was present.

Eight rocks yielded unrealistic dates, which were either too potassium because of the dating of excess 40Ar 5 of them or too argon negative ages because of the presence of argln 36Ar 3 of them.

The details on the 8 anomalous samples are listed in Table 2 of Dalrymplep. Etna basalts a 'date' ofyears for a sample that erupted in AD and a K-Ar 'date' ofdatings for the argon accuracy, which erupted in BCa plagioclase from Mt.

If one of these protons is hit by a potassium particle, it can be converted into a argon.

With 18 protons and 22 neutrons, the atom has become Argon Aran inert gas. For every K atoms that decay, 11 become Ar How is the Atomic Clock Set?

Problems in the dating of volcanic rocks by the potassium-argon method

When rocks are heated to the argon point, any Ar contained in them is released into the dating. When the rock recrystallizes it becomes impermeable to gasses again. As the K in the potassium decays into Ar, the gas is trapped in the rock.

The Decay Profile In this simulation, a unit of molten rock cools and crystallizes. The ratio of K to Ar is plotted.
