Description
Agate formation isn’t 100% understood, but the general idea is that hot water seeps into empty pockets in the limestone bedrock. The hot water carries large amounts of silica, which deposit as the water slowly evaporates. It’s often thought that the water which forms them is closer to a gel due to the heat and pressure involved in their formation As time goes on, the agates will form in bands. We’re still not quite sure if they form from the outside in or the inside out. Both theories have valid points, and the truth is that both could be true, it depends on the region in which they form.
