This specimen shows it's spheroid ancestry better than most, and the interrupted fill sequence allows easier investigation into what has happened to this point.

Cool! I wonder if any physicists have ever gotten around to analyzing the patterns of agates by determining their dimensional/fractal order and whether they follow the classic Feigenbaum constant of period doubling as a way of explaining their formation? Seems to me that things like agates that band for awhile and then become "slackers" might lend themselves to explanation by nonlinear differential mathematics and chaos theory. There appears, to the eye, that there is pretty definitely some sort of attractor involved that might explain for once and all how these things occurred. The same would apply to patterns in fine jaspers. I happened upon some graphs of the the wave propagation in the Beluzov-Zhabotinsky ( link: ) chemical reaction that are the spitting image of the patterns in Ocean and other poppy jaspers and in Flowering Tube Onyx. Just wondering out loud. There is still much disagreement over how agates form and I just finished a long read on the history of modern physics and chaos theory. Spheroids are well studied dynamical systems and chaos theory principles have been used to fully understand lots of things like flows and arrythmias in the heart, chemical mixing, thermodynamics, aerodynamics and lots of other things that were only narrowly understood from a one or two dimensional aspect. That's why so much science and medicine has been largely trial and error until the late 1970's, mid- 80's. Anyhow, though not a world changer, it sure would be neat to see these things investigated.

Rick How could anyone disagree? James Gleick's "Chaos" book opened our eyes how nature is naturally mathematical in an awesome way. Thanks for your comments!

Yep - That's the book I was reading. I'm interested in that stuff because I'm a Fractal Artist who is fairly well known. Google "Rykk" and you can find lots. I sell limited edition prints worldwide. Website's down as my host got divorced and the wife got his server, but there's still displays at Renderosity and Deviant Art, along with MOCA in NYC where I've won their international show twice.
Anyhow, it was the markedly fractal nature of the patterns in agate and other rocks that flung me way off of the art obsession and into a full-blown fascination with the natural fractals within rocks. Reading the book, along with a fair knowledge of math sort of explained to me the - potentially - why and how of this stuff. C-ya, Rick
