Having said that, numerous lunar rocks have such large volumes of what’s regarded as excess argon that dating by K/Ar isn’t also reported. (77, p. 200)
The citation because of this statement is always to a report by Turner (128). Turner, nevertheless, made no comment that is such extra argon in lunar rocks, and there are not any information inside the report upon which this type of summary might be based. The declaration by Rofahl and Segraves (77) is merely unjustifiable.
Volcanic stones made by lava flows which happened in Hawaii into the years 1800-1801 were dated because of the potassium-argon technique.
Extra argon produced obvious ages ranging from 160 million to 2.96 billion years. (77, p. 200)
Comparable rocks that are modern in 1801 near Hualalai, Hawaii, had been discovered to offer potassium-argon many years including 160 million years to 3 billion years. (92, p. 147)
