Having said that, many lunar rocks contain such large volumes of what’s regarded as being extra argon that dating by K/Ar just isn’t also reported. (77, p. 200)
The citation because of this declaration would be to a report by Turner (128). Turner, nevertheless, made no such remark about extra argon in lunar rocks, and there are not any information in the report on which this type of summary could possibly be based. The declaration by Rofahl and Segraves (77) is actually unjustifiable.
Volcanic stones made by lava flows which happened in Hawaii within the full years 1800-1801 were dated by the potassium-argon technique.
Extra argon produced obvious many years 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 which range from 160 million years to 3 billion years. (92, p. 147)
