(edit: After I had posted this Randy Korotev finally got back to me with a list of terrestrial granites that match the composition of those mentioned in the article, as did my stone; What, now, needs to be done is make sure the list is genuine, and, if it is, have a test for isotopes conducted.)
"lunar granites. Oxide units are wt%. Element units are ppm.
