<HTML>Doug and Pete,
>>Further to David's question and Anthony's response, yes, the dating method deals exclusively
with quartz. Oolitic limestone does contain quartz, but the common limestone found in
Mediterranean countries, and the one used for the pyramids, is nummulitic (which is the one
David is asking about) -- made of of course nummulites.<<
I will try to contact Professor Ericson. I think granite has more quartz in it and I wonder if it would be suitable for this kind of testing. There is granite in the Khufu pyramid and in the Khafra temples.
