Having said that, numerous lunar rocks contain such big amounts of what's regarded as being extra argon that dating by K/Ar just isn't also reported. (77, p. 200)
The citation with this declaration would be 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 in the report by which this type of summary might be based. The declaration by Rofahl and Segraves (77) is just unjustifiable.
