Mt etna radiometric dating
Plenty of time for the process to reach steady state by uniformitarian standards. So there would be very little Helium left in the rock.
New lava dome
Why would we expect a young dacite that is full of zoned phenocrysts to give one uniform date? Other ways you can help Donate: Again, a K-Ar date on such an impure 'fraction' would be meaningless and a waste of time and money. This is assumed to be immaterial, but can change the end results drastically. Obviously, it's Austin's improper use of the K-Ar method and not the method itself that is flawed.
These include the occlusion of xenoliths and xenocrysts, which are basically contaminants from existing old rocks that get mixed in with the magma; and phenocrysts, which are crystals of all sorts of different minerals that form inside the rock in different ways depending on how quickly the magma cools. Lassen plagioclase and the Mt.
Incremental heating experiments on 12 samples of sanidine yielded 46 data points that resulted in an isochron age of 94 years. Others are from larger asteroids that got hot enough to melt and send lava flows to the surface.
As expected, the purest pyroxene fraction provides an older date 2.
Again, the observable science fits the Creation model and not the uniformitarian model. Because intrusive rocks solidify deep within the Earth away from cool water and air, volcanic glass is absent and the grains may be fairly large that is, easily reaching lengths of one centimeter or more.
Again, because Swenson does not provide any page numbers when referring to Dalrymplewe can only guess which sections of Dalrymple's article he is citing.

These dating methods rely on a series of assumptions about the amounts of the parent-daughter elements, and a constant rate of decay. September 24, at 6: In the early mt etna radiometric dating of August 24, 79 CE, Mt Vesuvius erupted violently, mt etna radiometric dating hot ash flows speeding down its flanks. Long before Madam Curie and the invention of radiation detectors. This means that if you have atoms of 40 K, 1.
In particular, YECs attempt to demonstrate that excess argon is a 'problem' for K-Ar dating by locating examples of historically erupted volcanics, which yield K-Ar dates that are hundreds of thousands or millions of years older than their eruption dates.

Arndts R, Overn W. Link to other Andrew Snelling Rebuttals. They claim that these pieces of old rock xenoliths contaminated the sample and gave the very old age.
Polonium is very unstable, and decays quickly. Without properly referencing Bartelt et al. Dana21st ed. Even IF 1 Austin's summation of Heliker is absolutely accurate and no gabbro xenoliths or xenoliths of any other lithologies were present in the dacite, 2 Austin succeeded in removing all of the 'lithic inclusions' from his samples as Swenson claims, 3 no microscopic xenocrysts were hiding in this messy dacite, and 4 hypothesis 2 was not a factor, Austin would still need to specify the lifespan of the 'recent magmatic system.
