I would be interested in the standard "Callahan Sample" of a 35mm film container full (with lid taped on!). I only have time to check the frequencies, way behind with nursery trials. So if you (or any one else) like to post a sample to Gil Robertson, P.O. Box 51, Port Lincoln SA, AUSTRALIA 5606, I will check it as soon as possible. If you have a Paramagnetic reading or analysis, please include. Also please identify the origin if known, such as "rock type" from "xyz's Quarry" at "location". Other information of interest, if available is the geological age of the rock and the name of the geological series, if this is known. (I do not expect most people to have access to this, but I may have that information, if enough detail is given.)
It would seem that the more recent intrusive rocks, such as the basalts of SE South Australia and some in the Sydney Basin in NSW are of more interest than the older rocks, some of which are of little interest. It would also seem that within the same system, there is great variation. The Granite in my farm is about 6000, while the same series in a commercial quarry, only ten kilometres along the formation is under 100!!!! In the Sydney Basin, there are huge differences. We also note that active volcanic areas are known for producing very healthy food and thus healthy people, so it may be that the particular qualities of interest are lost over time.
