I am Matt Boeck and I am a rock hound and mineral enthusiast. I have been the past President for the Palomar Gem and Mineral Society 2008/9 I like Pegmatite minerals. I do beach collecting for Spherulitic rocks and am involved in their study and classification.
What you are seeing are Spherulites; a radiating crystal of amorphous structure that is joined in the center. The rock type is typified by a red brown 'oxblood red' color.
The term Spherulite is not an actual mineral but is a description of a process for more on Spherulites see this link to Wikipedia; http://en.wikipedia.org/wiki/Spherulite_(polymer_physics) it was helpful to me. Other spherulitic rocks (although not minerologically the same) include, Ocean Jasper, the Chrysanthemum stones (rhyolitic) from China, Snow Flake Obsidian, Thomsonite.
- Good collecting- MB
