A geode forms in a pocket or hollow circular shaped opening in sedimentary or igneous rock. The opening could be created by a gas bubble, a rotted organism, or by other means. Mineral filled solutions seep into the opening and gradually form crystals from the hole lining inward. If the hole completely infills, it becomes a nodule. Because the minerals that form inside the pockets are often silicate, they are resistant to weathering. This means that the rock surrounding the pocket may not be as resistant to weathering as the geode pocket. Once the surrounding rock has weathered and eroded, what remains on the surface is the geode or nodule. Once an empty circular shaped hole it is now a rock formation unto itself.
