Re. Brzy’s Formation of Agates Nov. 7, 2010 artical, the process of water needing to go back out of a cavity after depositing chalcedony (agate)to get new chalcedony molecules then transport it back into the cavity to deposit a new band may not be necessary if the mechanism of diffusion is considered. I think it would be found that if one were to take two soda bottles and fill them with water, with one of them containing say two tablespoons of salt then seal them together with a rubber tube. Then set them down side by side for a day then empty both out in two separate dishes to dry. One tablespoon of salt would be found in each of both dishes. The water does not need to go out and grab more mpolecules of salt then transport them back into the other bottle. The salt molecules travel by diffusion alone into the other bottle until both bottles have equal amounts of salt. The water does not go anywhere. further, what takes place of the water in the cavity if it has to leave the cavity to go get more SiO2 molecules? A test of whether the water goes anywhere might be proved if the water molecules were tagged with a radioactive isotope of oxygen in the H2O molecules. There should be very little radioactive water found it the bottle where the salt was first dissolved. Diffusion is defined as molecules of one substance moving from from an area of high concentration to an area of low concentration. This may also be seen if a coloring agent were used instead of salt.

I am a long time jade hunter from Wyoming. I see in this article that jadeite has been found in Wyoming. All the rockhounds I know say there is no jadeite in Wyoming, it is all nephrite. Would love to see a article on why there are so many different colors of green nephrite but only one color of green jadite which is always emerald green? I have 100 gram piece of emerald green jade and would like to know if this piece could be jadeite? Thank you Robert Martin

Your article on Agate Hill, Panguitch, Utah (Rock&Gem Feb 2008)should be retold. I was there last month for the second time and it is unbelivable the amount of agate and jasper scattered over the hill. A great place to take kids for their first hunt. So many pieces, it pays to be selective.

Excellent article and easy to understand explanation. How do I go about getting permission to post part of the article in my upcoming news letter? Giving proper credit to you the author and link to the site would not be a problem.
