  • How Do Agates Form?

    Sep 01, 2001It's like asking, How do you stop an agate: For the secret to making an agate, Heaney believes, is how silica (silicon dioxide, or SiO 2) dissolves in water. An agate starts with a cavity, a void in the rock. The best are found in basalt, a young volcanic rock. Volcanic rocks that erupt to the surface and harden contain a lot of water and
