Charles, I know that you directed the question to Zeev, and if I may be allowed, I would like to address a couple of your questions and then Zeev can also respond. Magnetite is well know to those who seek gold. It is frequently associated with placer deposits of gold and in fact contains some gold. The common name is "black sand". It is fairly dense and therefore concentrates in placer deposits like the gold. It is in fact, magnetic. It can be separated in the pan by a magnet. An interesting aside here is that the highest values found on the Oro Grande were associated with "reduced iron complexes" which are most probably magentic. Without specific references at hand, let me confirm from former readings that the magnetic polarity of the earth has shifted many times throughout its geologic history, and that record is frozen in the rocks. That would occur as molten rock containing magnetic elements cooled during a certain polarity. Once solid, the magnetic shift would not induce any change in the rock. There is some speculation as to what physical changes a polar magnetic shift might create on the earth. Well, that is about all that I know on the subject. Jack
